URL To Featured Image allows you to use an image hosted anywhere on the internet as the featured image (post thumbnail) for any post, page, or custom post type.
Perfect for: 
– Using CDN-hosted images as thumbnails. 
– Saving server space by not uploading large images. 
– Dynamically updating featured images from an external source.
Key Features: 
– Simple URL field in the post editor. 
– Works with posts, pages, and custom post types. 
– No extra database tables. 
– Fully compatible with WordPress themes and loops. 
– Uses standard WordPress functions like <code>the_post_thumbnail()</code>. 
– Ability to save the target image in the media libary if needed
How it works: 
When displaying the post, the plugin replaces the default WordPress featured image with the one provided via the URL.
