It's all in PHP currently.
Right now it does many of the things
http://www.freehostedgalleries.com/ does for you, except that it also has a content management system built in so you can easily add galleries from sponsors. Builtin thumbnail chooser (similar to Autogallery SQL but much better).
A friend suggested that some damn easy and simple TGP software is desperately needed and I thought it sounded like an interesting challenge. I have been mainly working on the backend(read: admin areas), to find out what I can automate, and how much.
