Great plugin - Just discovered it and also got your Sort Order addon - saved me a bunch of programming time.
I have an image in a "Front Page Slides" custom post type that returns a media ID for an image and not a URL where I want to show a scaled down pic in the back end.
Would be great to show the image using the built in wp_get_attachment_image( $id, $size ) function with an optional size specification.
Right now, I'm cheating and using the thumbnail view using "media library icon" as the way to view.
Anyway.. thanks again for a great plugin...
