Yesterday my plugin 'WP Easy Gallery' was temporarily removed from the repository. This plugin uses the prettyPhoto script as an image gallery. The admins claimed this script is not GPL, yet the author's website states that it is (http://www.no-margin-for-errors.com/projects/prettyphoto-jquery-lightbox-clone/). I have also noticed that some other plugins are using prettyPhoto, but have been left in the repository. Has anyone else experienced this problem?
