WordPress Flickr Embed is a WordPress plugin that provides an interactive interface for adding Flickr images to your posts. The interface is conveniently launched from the visual editor toolbar.
This is a fork of the (https://wordpress.org/extend/plugins/wordpress-media-flickr/) plugin for WordPress and provides numerous bug fixes and enhancements over the original.

This Plugin allows to use an external image as Featured Image, this can be especially useful if you house your images in another location.
This Plugin is compatible with Nelio External Featured Image Metadata, so you can reuse your data in case you want to uninstall Nelio Plugin.

External URL Featured Image

It is what I was looking for: simplicity.

$external_image = get_post_meta( $post->ID, '_dcms_eufi_img', true );

Works well for me

Use an external url image as Featured Image for your posts, pages, and other kind of post types.
