How to Fix Common Image Issues in WordPress

Here are some possible reasons why you might be seeing it:

  • Images not uploading – Maybe your images are too large, or WordPress is blocking them.
  • Broken or missing images – This happens if the image link is incorrect or the file was deleted.
  • Blurry images – WordPress might be resizing your images poorly.
  • Slow-loading images – Large images or missing caching can slow things down.
  • Images not showing after migration – If you moved your site, the image paths might be wrong.

Here are some common image issues in WordPress and how to fix them:

1. Images Not Uploading:

  • Check the file size limit in Media Settings.
  • Increase PHP upload limits via wp-config.php or php.ini:
     
    @ini_set( ‘upload_max_size’ , ‘256M’ );
    @ini_set( ‘post_max_size’, ‘256M’);
    @ini_set( ‘max_execution_time’, ‘300’ );
  • Ensure proper folder permissions (wp-content/uploads should be 755 or 775).

2. HTTP Error When Uploading Images:

  • Refresh the page and try again.
  • Disable plugins that might conflict with the media uploader.
  • Increase memory limit in wp-config.php:
     
    define(‘WP_MEMORY_LIMIT’, ‘256M’);
  • Change the image format (e.g., try JPEG instead of PNG).

3. Broken Images or Thumbnails Not Appearing:

  • Regenerate thumbnails using the Regenerate Thumbnails plugin.
  • Check image URLs (ensure they are correct and not leading to 404 errors).
  • If using a CDN, clear the cache.

4. WordPress Images Are Blurry:

  • Use high-quality images before uploading.
  • Ensure proper thumbnail sizes in Settings > Media.
  • Add the following in functions.php to ensure correct image sizes:
     
    add_filter( ‘jpeg_quality’, function( $arg ) { return 100; } );

5. Featured Image Not Displaying:

  • Ensure the theme supports featured images:
     
    add_theme_support(‘post-thumbnails’);
  • Check if the featured image is set correctly in the post editor.

6. Images Not Loading After Migration:

  • Update image URLs using the Better Search Replace plugin.
  • Ensure the uploads folder is correctly transferred.

7. Images Load Slowly:

  • Use image optimization plugins like Smush or Imagify.
  • Enable lazy loading (built-in since WordPress 5.5).
  • Serve images via a CDN like Cloudflare or BunnyCDN.
