Image is not fully displayed after clicking on the thumbnail in the gallery. How to fix this issue?

The issue of an image not fully displaying after clicking on a thumbnail in a gallery can be caused by several factors, including incorrect image dimensions, server issues, browser caching, or plugin conflicts. Here are some steps you can take to troubleshoot and fix this issue:

1. Check Image Dimensions: Ensure that the images you are using in your gallery have the correct dimensions. Images that are too large or too small may not display properly when clicked on. You can use an image editor like Adobe Photoshop or GIMP to resize your images to the recommended dimensions for your gallery plugin or theme.

2. Clear Browser Cache: Sometimes, the issue may be due to your browser cache. Clearing your browser cache can help resolve this issue. To do this, go to your browser settings and look for the "Clear Cache" or "Privacy" option.

3. Check Server Issues: If you are using a shared hosting service, the issue may be due to server overload or other server-related issues. You can try contacting your hosting provider to see if they can help resolve the issue. Alternatively, you can try uploading the images to a different server or using a content delivery network (CDN) to serve your images.

4. Disable Plugins: If you are using a plugin to display your gallery, try disabling other plugins to see if they are causing the issue. You can also try using a different gallery plugin to see if the issue persists.

5. Check File Permissions: Ensure that the files in your gallery have the correct file permissions. Incorrect file permissions can prevent the images from being displayed properly. You can use an FTP client like FileZilla to check and modify file permissions.

6. Update WordPress and Plugins: Make sure that your WordPress installation and plugins are up to date. Outdated plugins or WordPress versions can cause compatibility issues and other problems.

7. Use a Content Delivery Network (CDN): Using a CDN can help improve image loading times and ensure that images are displayed properly. CDNs distribute your images across multiple servers, reducing the load on your server and ensuring that images are served from the closest server to your visitors.

8. Use a Lightweight Gallery Plugin: If you are using a heavy gallery plugin, try using a lightweight alternative. Heavy plugins can cause performance issues and may not display images properly. Lightweight plugins like NextGen Gallery or WP MediaFolder can help improve gallery performance and ensure that images are displayed properly.

9. Check Image File Types: Ensure that the images you are using are in the correct file format. Some file formats, like BMP or TIFF, can be large and may not display properly in a gallery. JPG or PNG files are the most commonly used formats for web images.

10. Use a Thumbnail Generator: If you are generating thumbnails on the fly, try using a thumbnail generator plugin like Regenerate Thumbnails or EWWW Image Optimizer. These plugins can help generate the correct thumbnail sizes for your gallery and ensure that images are displayed properly.
