I need a web application that users can install and run on their own servers:
1) the ability to create and manage photo galleries and have them password protected
2) the ability to leave comments ON the photos themselves on particular areas of photos that will later be able to be seen by the adminstrator
3) the photos must transition with a book flip like transition in the middle of the photo
4) the ability to have users communicate to the admin when their comments are finished.
