This plugin is fantastic for locating pertinent images, but its not configurable enough to meet my needs. I tried it out and had to uninstall it.
I attempted to customize the way that credits display, to put them in a caption, and the plugin essentially ignored all my modifications and went with the default. I wanted to use captions to credit image owners, and didn't want the other contributors to my site to have to mess with code.
The image retrieval functionality is stellar, but the insertion into a WordPress post is tacky.
