If you are a blogger, you know the importance of featured images. Besides creating stunning content that helps users, featured images also play a vital role in the blogging and marketing journey.

It grabs website visitors’ attention, and in this way, you can provide a better user experience.

But what if the featured images are not loading?

If you are a WordPress user and the featured images of your blog posts are not functioning correctly, don’t worry. Many users are facing this issue. Here is everything you need to know about WordPress featured images and how to troubleshoot them.

Here are eight methods to fix the issue where the WordPress featured image isn’t loading.

What Is WordPress Featured Image

WordPress featured images are visual elements that represent blog posts or pages. When you visit the blog or archive page, they will be visible in the front end beside the post title.

It primarily conveys the article’s content and visually helps the website owner convey its message or theme to the reader.

In addition to the functions mentioned above, the featured image will be used on social media when someone shares your blog posts or pages. Hence, having a featured image is mandatory.

Why Featured Images Don’t Load Properly

WordPress featured images aren’t loading correctly due to multiple issues. Some of the common problems are:

• Server resource issues: If you use a shared hosting provider, you will have limited resources. If your storage or bandwidth quota is exhausted, the website will not work correctly.
• Corrupted files: If the image files are corrupted, they won’t load properly. The best thing you can do in this situation is restore a previously generated backup.
• Browser caching issues: Sometimes, browser caching is the culprit. Please clear the browser cache and see if you still face the problem.
• Permission issues: This could be a valid reason for not loading featured images properly. If the user or folder permissions are inaccurate, there will be conflicts.
• Conflicts on the site: If the website has any code or plugin conflicts, that can cause issues.

And so on.

Now you know why the featured images aren’t loading properly on the website’s front end. The following section shows you how to fix the issue where the WordPress featured image isn’t loading.

How to Fix the WordPress Featured Image Not Loading Error

Here are eight methods you can use to fix the featured image not loading error. They are:

• Check if you have assigned a featured image
• Disable lazy loading
• Check the theme settings
• Regenerate thumbnails
• Increase the default memory limit
• Change user permissions
• Modify the functions.php file
• Find and fix plugin or theme conflicts

Below, we will explain in detail how you can fix these issues. Without any further ado, let’s get started with the guide.

1. Check If You Have Assigned a Featured Image

The first thing you need to do is check if you have assigned a featured image. When you open the Gutenberg or Classic Editor, you will see the featured image option on the right-hand side.

If you can see an image there, you’re good to go. Here’s an example of a blog post with a valid featured image.

In some cases, you won’t see any image there. This means the blog post is missing its featured image.

You can choose one from the media library if you do not see an image in the field.

In some rare cases, you won’t see the featured image panel in the Gutenberg editor or Classic Editor. If you can’t see the option to add a featured image to the article, don’t panic. This is just an issue of visibility.

Click the three dots option on the top right-hand side of the Gutenberg editor. From there, choose preferences.

Now open the panel’s section. If you see the featured image panel as disabled, simply enable it.

From now on, the Gutenberg editor will show the featured image section on the right-hand side. If you use the Classic Editor, open the screen options and enable featured images from there.

Once you have made these changes, check your blog or category archive from the front end. If you can see the featured images, that’s great. If you have no luck, keep reading this guide.

Next, let’s move to the second option, turning off lazy loading to fix the WordPress featured image not loading issue.

2. Disable Lazy Loading

Lazy Loading is an excellent way to optimize image delivery. If you are running a blog where you teach tutorials, you might be adding tens, or maybe hundreds, of screenshots to the content (depending on how deeply you’re covering the topic).

By default, when someone lands on your post or page, the server will try to load the entire content before displaying the article. Hence, if you have multiple images in a blog post, loading a fully rendered webpage will take a long time.

The best way to fix this situation is to use lazy loading.

With lazy loading, images are loaded only when the user interacts with them. As the user scrolls, the server will load the pictures. This will help you with the performance optimization.

In some cases, lazy loading can cause issues with featured images. If you have enabled lazy loading on your website, it affects all the photos available.

Hence, try turning off lazy loading and check if the issue persists. Use a dedicated lazy-loading plugin like BJ Lazy Load, or a performance plugin like Perfmatters, for the feature.

You can turn off the option from the settings and try the website.

3. Check the Theme Settings

WordPress themes like Astra, GeneratePress, and Divi have dedicated featured image settings. If you do not see any featured images on the front end of the website, check the theme options.

On our dummy website, we have installed Astra.

If you open the WordPress customizer, you can see featured image-related options.

By default, you can see options like

• Image ratio
• Hover animation
• Image size

And so on.

Ensure the featured image element is visible when enabled. If you have added a featured image via the Classic or Gutenberg editor and turned off the featured image in the theme settings, your website will not display any featured images.

Depending on the theme you are using, the customizations will change. However, most modern WordPress themes include a dedicated panel where you can enable/disable theme-specific features.

If you still have issues with the WordPress featured images, move on.

4. Regenerate Thumbnails

If you recently switched WordPress themes and the featured images are not working well, it is because of the image sizes. WordPress theme developers will add custom image sizes to the theme, which will work well with the design.

If you recently changed your theme, you need to regenerate the image files to resolve the issue. WordPress doesn’t include this feature by default, so we’ll use a plugin called Regenerate Thumbnails.

First, install and activate Regenerate Thumbnails on your website.

Under WordPress tools, you can see the plugin’s settings.

You can see all the image sizes available on your website there.

All you need to do is click the Regenerate Featured Images button.

According to your media library size, the process will take a few minutes. Once the process is completed, you can check the website from the front end. If you have issues with the current featured image size, use this code to add custom image sizes to the WordPress installation.

add_image_size( new-featured-image, 1200, 720); // Custom Featured Image Size

You must modify the values and paste this at the end of the functions.php file or a site-specific plugin like Code Snippets. After saving the code, a new image size will be available, and you can choose the same for the featured images.

If the issue persists, proceed to the next stage. Next, we will teach you how to increase the WordPress memory limit and fix the WordPress featured image not loading issue.

5. Increase the WordPress Memory Limit

Every WordPress website has a pre-defined memory limit. Usually, your web server configures this, and the default value is 32 MB or 128 MB. Increasing the WordPress memory limit is another effective way to address multiple problems.

Upgrading this won’t cause any resource consumption spikes or any instabilities. To increase the WordPress memory limit, you need to copy this code:

define( 'WP_MEMORY_LIMIT', '256M' );

Now, you need to open the wp-config.php file. You can access the wp-config.php filer via a dedicated file manager plugin or an FTP client such as FileZilla.

In this case, we will use the Filester plugin. After installing and activating the plugin, find the wp-config.php file. Now, perform a right-click and choose the code editor option.

Just before the line says /* That’s all, stop editing! Happy publishing. */, paste the code. That’s it! Save the file; now your website’s memory limit is 256MB!

Some WordPress hosting companies offer a dedicated option in the account panel to manage the memory limit. If you use a premium managed WordPress hosting provider, look for an in-house option to boost the WordPress memory limit.

If you need help on the go, contact the web hosting provider’s support team.

6. Change User Permissions

If you are running a multi-author blog and the users do not see an option to upload featured images while writing blog posts, it is because of a permission issue. With the User Role Editor plugin, you can customize permissions.

So, install and activate the plugin on your website.

After activation, you can see the plugin’s settings under WordPress settings.

You can do it from there if you need to tweak some options. Once you have done that, go to Users and User Role Editor.

From the dropdown, you can choose the user role.

Now, ensure the file upload permission is enabled for the user role.

Save the settings once you’re done. The following section will show how to modify the functions.php file to add featured image support.

7. Modify the Functions.php File

If you use a custom-developed WordPress theme, you must first add support for featured images. Otherwise, you won’t see the featured image meta box in the Gutenberg or Classic Editor.

Here’s how you can do it.

The first thing you need to do is copy this code:

add_theme_support('post-thumbnails', array(
'post',
'page',
'custom-post-type-name',
));

Once you have copied it, paste it into your child theme’s functions.php file or a site-specific WordPress plugin. After that, you can save the file.

From now on, you’ll see a featured image meta box in the editor. If you can’t see it, it is because of your caching. You can clear your website cache and recheck it. Next, let’s see how to fix the WordPress featured image not loading by identifying the theme or plugin causing the issue.

8. Find Plugin/Theme Conflicts

You might use multiple third-party plugins or code when running a WordPress website or WooCommerce store. Sometimes, these can cause compatibility issues with your website and require it to be fixed.

If you have started experiencing the featured image not loading issue after installing/updating a plugin or theme, it means the updated theme or plugin is causing the problems.

A plugin called Health Check & Troubleshooting is available to find related issues. You can install and activate this plugin if you need help finding site-related issues.

After activation, you can see the plugin’s settings under WordPress tools.

The plugin will show you all the issues that need attention.

You can fix those, and your website will start working as usual. If you still can’t find the problem, enable the troubleshooting mode and start deep troubleshooting.

Usually, any of these eight methods will help you fix the WordPress featured image not loading issue.

How to Add a Default Featured Image in WordPress

If you need to use a single featured image for all your articles, keep reading this section. We will show you how to add a default Featured image in WordPress without hassle.

For that, we will use a plugin called Default Featured Image. You must first install and activate the plugin on your WordPress website or WooCommerce store.

Now, open the Media settings, which you can see under WordPress settings.

You can see the option to add a default featured image for your posts.

From the media library, you can choose an image you like. Once you have done that, save the changes.

That’s it! WordPress will add the default featured image when you publish new blog posts. You can manually override the image whenever you like. Or if you do not need to use a default featured image for your posts, click the don’t use a default featured image button.

Next, let’s see how to bulk-edit featured images in WordPress.

How to Bulk Edit Featured Images in WordPress

If you need the option for editing featured images in bulk, continue reading. Bulk editing featured images will come in handy in multiple situations. For example, a bulk editor plugin will be helpful if you have published hundreds or thousands of blog posts and need to update their featured images.

Since WordPress doesn’t have this feature by default, you must rely on a plugin for this task. Here, we will be using Quick Featured Images for bulk editing. First, install and activate the plugin on your website.

After successful activation, you can see the plugin’s settings on the left-hand side.

Now, choose the bulk edit option.

You’ll be redirected to the editor now.

As you can see at the top of the page, there are five things you need to do to perform a bulk edit:

• Select the image from the media library
• Add a filter if required
• Refine it
• Confirm the changes
• Start deploying the changes

From the media library, choose an image and go to the next step. There, you will see extra options.

Select the suitable options according to your preferences. The plugin will show you all the applicable blog posts/pages or custom post types with the new featured image. If you are happy with the result, apply the changes.

You can perform this task with either one or multiple featured images.

Now you know how to bulk edit featured images in WordPress. As you can see, many plugins are available for handling featured images on a website. Let’s look closely at some of the options in the next section.

Troubleshooting

• Incorrect file permissions: Featured images may fail to load if your uploads folder lacks the required permissions. Set /wp-content/uploads/ to 755 to ensure WordPress can read and write files correctly.
• Low PHP memory limit: A low memory limit can cause image uploads or processing to fail. Increase the limit in wp-config.php or through your hosting panel to avoid image handling errors.
• Conflicts with caching plugins: Page caching or CDN caching may serve outdated media files. Clear all caches, temporarily disable the caching plugin, and purge your CDN to check if the image loads correctly.
• Theme missing thumbnail support: Some themes don’t register featured image support. Add add_theme_support('post-thumbnails') to your theme’s functions.php file to enable featured images.
• Image size not generated: If a new theme uses different thumbnail dimensions, the old thumbnails won’t match the new ones. Use a thumbnail regeneration plugin to create the correct sizes.
• Broken image URLs: Incorrect WordPress Address or Site Address settings can generate invalid image paths. Verify both URLs in Settings > General and correct them if necessary.
• Plugin conflicts: Optimization or security plugins may block image rendering. Disable plugins one by one to find the conflict, then reconfigure or replace the problematic plugin.
