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.

No more edit the html of the iframe, put easily in block editor with height and width.
Great Job Jorge!!!

Great as simple

Works flawlessly, it does what it says it does and what it has to do. It's a perfect solution to show external contents with an iframe solution.

This is "a must" block.

Perfect solution for iframe content

Lo necesitaba, así evito añadir una colección de bloques para usar solo uno.

Sencillo y útil.

It is not necessary to create plugins with many functions, thanks Jorge for the contribution!

Simple and great

Easily insert iframes inside the block editor.
