In today’s digital world, visual content plays a vital role in capturing attention and enhancing user engagement. Whether you’re running a blog, portfolio, or online store, the way you display images on your website can make a significant difference in the overall user experience. WordPress, one of the most popular content management systems (CMS), offers a powerful platform for users to easily manage and showcase their content, including images.

One of the most effective ways to showcase images in WordPress is through image preview layouts. These layouts help organize and present images in an attractive and engaging manner, making it easier for visitors to navigate and interact with your content. Image preview layouts can range from simple grids to more complex designs like carousels or masonry layouts, each offering a unique way to present your images.

This article will guide you through the different image preview layout options available in WordPress, from the default options to customizable solutions through plugins and custom code.

What Are Image Preview Layouts in WordPress?

Image preview layouts in WordPress refer to the various ways you can display images or image galleries on your website. These layouts determine how your images are presented to visitors, influencing both the aesthetics of the site and how users interact with the visual content. Essentially, image preview layouts allow you to organize and showcase images in a visually appealing, user-friendly manner.

In WordPress, image preview layouts are typically used in galleries, blog posts, portfolios, or any content where images play a significant role. These layouts can range from simple arrangements like a single image within a post to more complex designs such as grids, carousels, or masonry layouts that display multiple images in an organized yet creative way.

The Role of Image Preview Layouts:

• Visual Appeal: A well-organized image layout helps break up text-heavy content and makes the website more engaging, increasing the chances that visitors will stay longer.
• User Experience: A clean, easy-to-navigate layout ensures that visitors can quickly find and view the images they’re looking for without frustration.
• Content Organization: Image preview layouts also help in organizing images in a way that aligns with the overall theme of the website, whether it’s for a product gallery, a blog, or a portfolio.

For example, a portfolio might use a sleek grid layout to display various projects, while an online store might use a product-focused grid to present items for sale. The right image layout can enhance your website’s design, making it both functional and visually captivating.

Why Choose Different Image Preview Layouts in WordPress?

Choosing the right image preview layout in WordPress is not just about aesthetics—it’s about enhancing the overall user experience, improving website functionality, and even boosting SEO. Different image layouts can serve specific purposes based on the content type, brand identity, and the goals you aim to achieve with your website. Below are some key reasons why you should consider experimenting with various image preview layouts:

1. Tailored to Different Content Types

Not all websites are the same, and different types of content benefit from different image layouts. A blog might use a simple grid to display images within articles, while a portfolio website might opt for a more sophisticated masonry or gallery layout to highlight creative work. Similarly, e-commerce sites often benefit from a uniform, clean grid layout that focuses on product images for better sales conversion. By using different layouts, you can better showcase the specific content you offer.

2. Boosting SEO with Properly Structured Images

Images play an important role in SEO. A well-chosen layout can help optimize images for search engines in several ways. For example, a layout that automatically sizes images to fit the screen or includes alt text can boost SEO rankings. Moreover, by choosing layouts that support image compression or responsive sizing, you ensure that your images load faster, improving both SEO performance and user experience.

3. Enhancing User Engagement and Navigation

Images are a primary way to capture a visitor’s attention. A thoughtfully designed image layout can keep users engaged and encourage them to explore more content. For example, interactive or dynamic image layouts such as carousels or hover effects can make the browsing experience more engaging, encouraging visitors to stay longer on your site. Additionally, well-organized layouts with clear categories or navigation ensure that users can easily find the images they are interested in, reducing bounce rates and improving overall site performance.

4. Customization to Fit Brand Identity

Your website’s image preview layout should reflect your brand’s identity and the message you wish to convey. For example, a minimalist brand might prefer simple grid layouts with plenty of whitespace, while a more creative brand could choose a gallery or mosaic layout to express its unique style. WordPress offers a wide range of layouts to choose from, whether through the default settings or by using plugins, allowing you to customize your site’s appearance to align perfectly with your brand.

5. Adapting to Mobile Devices and Different Screen Sizes

With the rise of mobile browsing, responsive image preview layouts have become essential. WordPress allows you to choose layouts that automatically adjust to fit mobile screens and different device types, ensuring your images are optimized and easy to view on all platforms. This adaptability is crucial for improving user experience and ensuring your site is accessible to a wider audience.

WordPress Default Image Preview Layouts

WordPress, as a versatile content management system, provides users with several built-in image preview layouts. While these default layouts are quite basic, they offer an easy and efficient way to display images without needing to install additional plugins or write custom code. In this section, we’ll explore the default image preview layouts that WordPress offers and how you can utilize them effectively for different types of content.

1. Single Image Preview

The simplest form of an image preview layout in WordPress is displaying a single image within a post or page. When you add an image to a WordPress post, it’s inserted as an individual element with a default alignment—left, center, or right. The image is typically displayed within the content area, and WordPress will automatically scale it according to the width of the post or page container.

When to use: This layout works best for posts or pages where you want to highlight one main image, such as featured images, product showcases, or large visuals that support the content. You can also use this layout for header images or banners.

2. WordPress Gallery Layout

WordPress also comes with a simple gallery feature that allows you to create a basic image gallery within a post or page. When you insert multiple images into a WordPress gallery, they are automatically arranged in a grid layout, with thumbnails of each image displayed. Users can click on any thumbnail to view the image in a larger, lightbox-style view.

Features of the default gallery:

• You can specify the number of columns (e.g., 2, 3, or 4) and decide how many images are displayed per row.
• Clicking on an image typically opens it in a popup or lightbox format, allowing for easy viewing of multiple images.

When to use: This layout is great for photo collections, portfolios, or any content where you need to display multiple images together in a neat and organized fashion. It’s simple to use and can be customized further with additional CSS for more control.

3. WordPress Masonry Layout (Via Block Editor)

With the introduction of the WordPress block editor (Gutenberg), users now have more flexibility in arranging images. One of the available block options is the Gallery Block, which allows images to be arranged in a masonry-style layout. This layout is similar to the grid, but with varying image sizes, creating a more dynamic and aesthetically pleasing presentation.

The masonry layout automatically adjusts to fit the size of the images, creating a non-uniform arrangement where images of different dimensions appear more naturally. This style adds variety to your content and allows for more creative freedom when displaying images.

When to use: Masonry layouts are perfect for blog posts, portfolios, or any content that requires a more fluid, creative way of displaying images. They work well for visual storytelling and provide a modern look to your website.

4. Slideshow/Carousel Layout (Built-in Blocks or Theme Features)

While not a traditional “layout” by default, WordPress themes often come with built-in options to create image carousels or slideshows. You can either use WordPress blocks or leverage theme-specific features to showcase a series of images in a rotating slideshow format. This type of layout allows users to view multiple images without leaving the page.

Features of the default carousel:

• Usually includes navigation arrows or dots to cycle through images.
• Can be set to autoplay or allow users to manually advance slides.

When to use: Carousel layouts are ideal for highlighting a series of related images, such as featured products, event photos, or project showcases. They provide an interactive experience, allowing visitors to engage with multiple images without navigating away from the page.

5. Thumbnail and Image Links

Another default option for previewing images in WordPress is using thumbnail previews linked to larger versions of the images. This can be done either manually or through the WordPress gallery, where small thumbnails are shown in a grid layout and users can click to view the full-size image. It’s a common choice for blogs and portfolios.

When to use: This layout is best for blogs or galleries where space is limited, and you want to provide quick access to images without overwhelming the content. It also works well in news articles or blog posts where images need to support the text but don’t require too much emphasis.

Popular Plugins for Custom Image Preview Layouts

While WordPress provides several default image preview layouts, sometimes you may want more control over the appearance and functionality of your images. This is where plugins come into play. Plugins can offer advanced features, customization options, and better aesthetics to make your images stand out. Here are some of the most popular plugins for creating custom image preview layouts in WordPress:

1. CodeCanel

Creating Different Image Preview Layouts Without Plugins

While plugins are a great way to enhance your image preview layouts, WordPress also offers built-in features that allow you to create beautiful and functional image galleries without relying on third-party tools. If you prefer to keep things lightweight and avoid installing extra plugins, you can still achieve various image layouts using WordPress’s native tools, along with some basic HTML and CSS. In this section, we’ll explore how you can create different image preview layouts without plugins.

1. Using WordPress’s Built-in Gallery Feature

WordPress comes with a built-in gallery feature that allows you to insert images into your posts and pages in a structured layout. When you add multiple images, WordPress automatically arranges them in a grid format. This simple gallery option is accessible through the Block Editor (Gutenberg) and the Classic Editor.

Steps to Create a Basic Gallery:

• Add Images: Go to the post or page where you want the gallery and click the “Add Block” button (if using the Block Editor).
• Select Gallery Block: Choose the “Gallery” block, and then click “Add Images” to select multiple images from your media library or upload new ones.
• Customize Layout: You can specify the number of columns (e.g., 2, 3, or 4) to organize the images. WordPress will automatically handle the spacing between the images.
• Linking and Captioning: You can also add captions, links, and alt text for each image, ensuring they are properly optimized for SEO.

When to Use: The default gallery layout is perfect for simple use cases like displaying product images, blog post thumbnails, or photo collections. However, the layout is fairly basic, so if you need more control over the design, you may need to add custom CSS (as explained below).

2. Customizing the Layout with HTML and CSS

For those who have a bit of coding knowledge, custom HTML and CSS allow you to create more intricate and personalized image preview layouts. With just a few lines of code, you can change how images appear on the page—whether it’s a sleek grid, masonry layout, or even a hover-effect gallery.

Creating a Simple Grid Layout:
If you want to display images in a grid format (similar to the WordPress default gallery but with more control), you can use the following HTML and CSS approach:

HTML:

<div class="custom-gallery">
    <img src="image1.jpg" alt="Image 1">
    <img src="image2.jpg" alt="Image 2">
    <img src="image3.jpg" alt="Image 3">
    <img src="image4.jpg" alt="Image 4">
</div>

CSS:

.custom-gallery {
    display: grid;
    grid-template-columns: repeat(4, 1fr); /* 4 columns */
    gap: 10px; /* spacing between images */
}

.custom-gallery img {
    width: 100%;
    height: auto;
    border-radius: 8px;
}

In this example, we use the grid-template-columns property to specify the number of columns in the grid. The gap property controls the spacing between the images, and the border-radius adds rounded corners to the images.

When to Use: This approach is ideal if you want more flexibility in how your images are arranged and displayed on the page, but without installing a plugin. It’s a great solution for users who want a custom, unique gallery style.

3. Creating a Masonry Layout with CSS

If you want to create a masonry-style layout (where images of different sizes fit together like a Pinterest board), you can achieve this effect using the column property in CSS. Here’s an example of how to do it:

HTML:

<div class="masonry-gallery">
    <img src="image1.jpg" alt="Image 1">
    <img src="image2.jpg" alt="Image 2">
    <img src="image3.jpg" alt="Image 3">
    <img src="image4.jpg" alt="Image 4">
</div>

CSS:

.masonry-gallery {
    column-count: 3; /* 3 columns */
    column-gap: 15px; /* spacing between columns */
}

.masonry-gallery img {
    width: 100%;
    margin-bottom: 15px;
    border-radius: 8px;
}

In this example, the column-count property sets the number of columns, and the column-gap controls the spacing between columns. The images will automatically adjust in size and fit together in the most efficient way.

When to Use: The masonry layout is ideal for showcasing a collection of images with varying dimensions, such as a portfolio or a photo album. It adds a modern, dynamic feel to your website, making it more engaging for users.

4. Using the Block Editor’s Gallery Block for Advanced Customization

The WordPress Block Editor (Gutenberg) has made it easier than ever to create custom image layouts, even without plugins. By using the Gallery Block in combination with custom settings, you can create simple yet attractive image layouts that suit your needs.

Customizing the Gallery Block:

• Image Alignment: You can adjust the alignment of images (left, center, or right) and set how they behave when viewed on mobile.
• Column Settings: WordPress lets you select the number of columns in your gallery (up to 6 columns).
• Spacing and Borders: With custom CSS, you can modify the spacing, borders, or hover effects of the gallery.

When to Use: This method works well for users who want to stick with WordPress’s built-in tools but require a bit more flexibility than the default gallery. It’s a great solution for content creators, bloggers, and small business owners who want a polished image gallery without relying on third-party plugins.

Benefits of Creating Image Layouts Without Plugins

• No Added Weight: By avoiding plugins, you reduce the overall bloat on your WordPress site, which can lead to faster load times and improved performance.
• Complete Control: Custom HTML and CSS give you full control over your layouts, so you can implement any design you want without limitations.
• No Compatibility Issues: Using native WordPress features ensures compatibility with your theme and other WordPress functionalities, preventing potential conflicts that may arise with plugins.

Best Practices for Optimizing Image Preview Layouts

Creating visually appealing image preview layouts is just the first step. To ensure that your layouts are not only attractive but also functional and user-friendly, it’s important to optimize them. Optimizing image layouts can improve page load speed, SEO rankings, and the overall user experience on your website. Below are some best practices to follow when optimizing image preview layouts in WordPress.

1. Use Proper Image Sizes

One of the most common mistakes when working with images is uploading images that are too large for the web. Large image files can slow down your website and cause delays in loading time, which negatively affects the user experience and SEO.

Best Practices:

• Resize Images Before Uploading: Ensure that images are the right dimensions for your layout. For example, a full-width hero image doesn’t need to be as small as a thumbnail image.
• Optimize for Retina Displays: If you’re targeting high-resolution devices, upload images at double the size, but still optimize them for file size.
• Use the WordPress Media Library: WordPress allows you to automatically resize images when you upload them. Check the default image sizes in the settings (thumbnail, medium, large) and use them accordingly.

Tools to Help:

• TinyPNG: This tool can compress your images before uploading them to WordPress, without compromising on quality.
• Smush Image Compression: A popular WordPress plugin that automatically compresses images as you upload them to your site.

2. Implement Lazy Loading

Lazy loading is a technique where images are only loaded when they come into the user’s view (as they scroll down the page). This greatly reduces initial page load times, especially for image-heavy pages like galleries or blogs with many posts.

How to Implement Lazy Loading:

• Built-in Lazy Loading: WordPress added native lazy loading support for images in version 5.5. Simply ensure your WordPress site is up-to-date, and images will automatically load lazily.
• Use Plugins: If you need more control over lazy loading, plugins like a3 Lazy Load or Lazy Load by WP Rocket can help.

Benefits:

• Faster page load times, leading to a better user experience.
• Reduced bounce rates, as users won’t have to wait for images to load before interacting with your content.

3. Optimize for Mobile Devices

More than half of all website traffic now comes from mobile devices, so it’s critical that your image preview layouts are responsive and optimized for smaller screens.

Best Practices:

• Responsive Design: Ensure that your image layouts are designed to adjust according to the screen size. Most WordPress themes are mobile-friendly, but you may need to tweak custom CSS for perfect responsiveness.
• Use Scalable Images: Consider using SVG images for logos and icons, as they scale perfectly on different devices without losing quality.
• Image Dimensions: For smaller screens, use smaller image sizes. WordPress allows you to set different image sizes for different screen widths via CSS media queries.

Responsive Image CSS Example:

@media screen and (max-width: 768px) {
    .custom-gallery img {
        width: 100%; /* Makes the images full-width on mobile */
    }
}

Benefits:

• Faster load times on mobile devices.
• Improved user experience on smaller screens, as images will automatically adjust to fit the display.

4. Use Image Compression Tools

Image compression is crucial for improving the speed of your website. Large images consume more bandwidth, which can significantly slow down your website, especially for users with slower internet connections.

Best Practices:

• Lossless Compression: Use image compression tools that reduce the file size without losing any visible quality. Tools like ImageOptim and TinyPNG offer excellent lossless compression for images.
• WebP Format: Consider converting your images to the WebP format, which provides high-quality images at a smaller file size than JPEG or PNG. Many modern browsers support WebP, and it’s supported by some WordPress plugins like WebP Express.

Tools to Use:

• WP Smush: Automatically compresses your images as you upload them.
• ShortPixel: A plugin that supports both lossy and lossless compression, as well as WebP conversion.

Benefits:

• Faster page load times, improving both user experience and SEO.
• Less bandwidth usage, especially for mobile users.

5. Add Alt Text and Descriptions

Alt text (alternative text) is essential for SEO and accessibility. It helps search engines understand the content of an image and makes your site more accessible to users with visual impairments who rely on screen readers.

Best Practices:

• Descriptive Alt Text: Use clear, descriptive alt text that accurately describes the image’s content. This helps improve SEO and provides context for users who cannot view the image.
• SEO-Friendly Descriptions: Including relevant keywords in your alt text can help improve your rankings in search engine results, but avoid keyword stuffing. Keep it natural and relevant to the content.

How to Add Alt Text:

• When uploading an image to WordPress, you can add alt text in the “Alternative Text” field in the Media Library.
• Review all images on your site and ensure that alt text is included for each one.

Benefits:

• Improved SEO, as search engines use alt text to index images.
• Better accessibility for users with disabilities, ensuring everyone can access your content.

6. Test and Monitor Layout Performance

Regularly testing the performance of your image layouts will help ensure that they are both visually appealing and technically sound. Use performance testing tools to check page load speeds and optimize any areas that may slow down your website.

Tools to Use:

• Google PageSpeed Insights: Provides an in-depth analysis of your website’s performance and gives actionable recommendations for improvement.
• GTMetrix: Offers detailed reports on how your website loads and how image optimization impacts performance.

Benefits:

• Helps identify issues that may negatively impact page load time or user experience.
• Allows you to monitor improvements and adjust your strategy based on real-world data.

Common Issues and Troubleshooting Tips for Image Preview Layouts

Even though creating and optimizing image preview layouts in WordPress can significantly improve the visual appeal and functionality of your website, there are a few common issues that users may encounter. Understanding these potential problems and knowing how to troubleshoot them can save you time and ensure that your website runs smoothly. Below are some of the most common issues and how to address them.

1. Images Not Displaying Correctly

One of the most common issues when working with image preview layouts is images not displaying correctly on the front end of your website. This could be due to several reasons, such as incorrect file paths, file permission issues, or even server-side problems.

Possible Causes:

• Incorrect File Paths: If the images are not showing, the first thing to check is the file path. Ensure the image files are correctly linked and located in the right directory.
• Broken Image Links: If images are missing or not appearing, there may be a broken link to the file or a mistake in the URL.
• File Permissions: If the image folder doesn’t have proper permissions, the server won’t be able to serve the images. Make sure the permissions are set correctly.

Troubleshooting Steps:

• Check the Image URL: Right-click on the missing image and open it in a new tab. If the image doesn’t show, the URL is likely incorrect.
• Verify File Permissions: Check the permissions for the /wp-content/uploads/ folder. You can do this through your file manager or FTP client. The correct permissions are typically 755 for folders and 644 for files.
• Re-upload Images: If images are missing or not showing, try re-uploading them from the WordPress dashboard.

2. Slow Image Load Times

If your image galleries or layouts take too long to load, this can result in a poor user experience and negatively impact your SEO rankings. Slow loading times can be caused by large image file sizes, a lack of image optimization, or a high number of images on the page.

Possible Causes:

• Large File Sizes: Uncompressed, large images can slow down your site. This is especially problematic if you’re displaying a lot of images in a gallery or a product page.
• No Caching or Lazy Loading: Without caching or lazy loading, all images on a page may be loaded at once, slowing down the page.
• Too Many HTTP Requests: If you have too many images or other resources (CSS, JS, etc.) on the page, it can result in too many HTTP requests, slowing down the page load.

Troubleshooting Steps:

• Use an Image Optimization Plugin: Plugins like Smush or ShortPixel can automatically compress and optimize your images for faster load times.
• Enable Lazy Loading: Enable lazy loading for images so that they only load when they enter the user’s viewport. This will help reduce initial load times.
• Use a Caching Plugin: Caching plugins like W3 Total Cache or WP Rocket can help reduce load times by caching static resources like images.
• Test with Tools: Use tools like Google PageSpeed Insights or GTMetrix to test your website’s speed and identify areas for improvement.

3. Images Not Scaling Properly on Mobile Devices

With more users browsing the web on mobile devices, it’s essential to ensure that your image preview layouts are mobile-friendly. Sometimes, images may not scale properly, causing them to appear distorted or cut off on smaller screens.

Possible Causes:

• Fixed Width or Height: If you’ve set fixed widths and heights for your images, they may not adjust correctly on mobile devices.
• Non-Responsive Design: If your theme or custom CSS doesn’t support responsive design, images may not scale or adjust properly to different screen sizes.

Troubleshooting Steps:

• Check CSS for Responsiveness: Use CSS media queries to make your images responsive. For example:

  img {
      width: 100%;
      height: auto;
  }

This ensures that images will scale according to the screen size.

• Use WordPress Themes That Are Mobile-Optimized: Ensure that the theme you’re using is mobile-responsive. Most modern WordPress themes are designed to be responsive out of the box.
• Test on Different Devices: Always test your image layouts on different devices (smartphones, tablets, desktops) to ensure they are displaying correctly.

4. Gallery Layouts Looking Messy or Misaligned

Sometimes, after adding images or galleries, the layout can become misaligned, with images overlapping or unevenly spaced. This is often due to CSS conflicts, incorrect gallery settings, or inconsistent image dimensions.

Possible Causes:

• Different Image Dimensions: When you use images of varying sizes in a gallery without proper CSS adjustments, they may cause misalignment.
• CSS Conflicts: If your theme or custom CSS conflicts with the gallery plugin or WordPress default styles, it could result in misalignment issues.

Troubleshooting Steps:

• Set Consistent Image Sizes: Use consistent image sizes for your galleries. Resize or crop images before uploading them to ensure they fit nicely together.
• Adjust CSS for Layouts: Use CSS to fix the layout. For example, setting a fixed width or height for images can help maintain alignment.

  .gallery img {
      width: 100%;
      height: auto;
      object-fit: cover; /* Ensures images fill the container without distortion */
  }

• Use Grid or Flexbox Layouts: Use CSS Grid or Flexbox to create a responsive and neat layout that adapts to different screen sizes and ensures images are properly aligned.

5. Images Not Being Indexed by Search Engines

If your images aren’t being indexed by search engines, they won’t appear in image search results, which can affect your site’s SEO performance.

Possible Causes:

• Missing Alt Text: Images without alt text won’t be indexed properly by search engines.
• Incorrect Image File Names: If your images have random file names like IMG_1234.jpg, they won’t be optimized for SEO.

Troubleshooting Steps:

• Add Alt Text: Always add descriptive alt text to your images. This not only helps with SEO but also improves accessibility.
• Use SEO-Friendly File Names: Name your image files with descriptive, keyword-rich names. For example, blue-widgets.jpg is more SEO-friendly than IMG_1234.jpg.
• Create an XML Sitemap: Ensure that images are included in your XML sitemap so that search engines can find and index them. You can use plugins like Yoast SEO or Google XML Sitemaps to help with this.

• Use a content delivery network (CDN) to serve images from multiple locations around the world, improving load times.

5. What is the difference between the WordPress Gallery and Image Slider?

A WordPress Gallery is a grid-based layout for displaying multiple images on a page. Galleries are static and usually display images in rows or columns, allowing for a clean and organized presentation.

An Image Slider (also called a carousel) displays images in a rotating or sliding manner, usually one image at a time. It is interactive and can be navigated by the user through arrows or automatic transitions. Sliders are ideal for showcasing a few images in a dynamic, eye-catching way.

6. How can I add hover effects to my image previews?

You can add hover effects to your image previews using CSS. For example, the following CSS will create a zoom effect on hover:

.gallery img {
    transition: transform 0.3s ease;
}

.gallery img:hover {
    transform: scale(1.1);
}

This effect enlarges the image slightly when the user hovers over it, creating an interactive experience. You can also use other CSS properties like opacity, color changes, or shadow effects to further enhance the hover effect.

7. How do I create a lightbox for my WordPress gallery?

A lightbox effect allows users to view images in full-screen mode without leaving the current page. Many WordPress themes and plugins offer lightbox functionality, but you can also implement one manually using a plugin like Simple Lightbox or Responsive Lightbox & Gallery.

If you want to manually create a lightbox effect, you can use a combination of HTML, CSS, and JavaScript. However, using a plugin is generally quicker and easier for beginners.

8. How do I fix images not showing up in my WordPress gallery?

If your images are not showing up in your WordPress gallery, try the following steps:

• Check image permissions: Ensure that the image files in your WordPress Media Library have the correct file permissions.
• Regenerate Thumbnails: Sometimes WordPress doesn’t automatically create all the required image sizes. You can use the Regenerate Thumbnails plugin to fix this issue.
• Clear browser cache: Sometimes, your browser cache may store an outdated version of your page. Clear your cache and try reloading the page.

9. How can I create a custom image preview layout without plugins?

To create a custom image preview layout without plugins, you can use HTML and CSS. For instance, using CSS Grid or Flexbox allows you to arrange images in creative layouts. You can control how images are displayed, such as the number of columns, spacing between images, or adding hover effects with custom CSS.

Example using CSS Grid:

.custom-gallery {
    display: grid;
    grid-template-columns: repeat(3, 1fr);
    gap: 10px;
}

.custom-gallery img {
    width: 100%;
    height: auto;
}

This creates a simple, responsive 3-column gallery layout.

10. Can I use SVG images in my WordPress image preview layouts?

Yes, you can use SVG (Scalable Vector Graphics) in WordPress, which are great for logos and icons as they scale perfectly without losing quality. However, WordPress doesn’t allow SVG uploads by default due to security concerns. You can enable SVG uploads safely using plugins like Safe SVG or by adding custom code to your functions.php file. Be cautious with SVGs, as they can carry security risks if not handled properly.
