This plugin shows a small toolbar over photos from Flickr embedded in your post. The toolbar buttons when clicked show Location, EXIF and lots more in a Thickbox
The Live Flickr Comment Importer Plugin features
<ul>
<li>Uses the inbuilt jQuery and Thickbox scripts.</li>
<li>Most calls to the Flickr API are done on the client side – so there is minimal additional load or delay on the server.</li>
<li>If your photo has geo-location data embedded, shows it as a marker on Google map with reverse geo-location to fetch the place name</li>
<li>Shows most interesting EXIF data first with option to show the complete raw data</li>
<li>Shows information like title, description, number of views and comments, tags on the photo, sets and pools the photo belongs to and links to various sizes if there is permission</li>
</ul>

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.
