This morning (since it is after midnight) I updated my Gallery install from version 1.5 to version 2 Beta 3.
The Gallery project moved to a database driven system and the administration console is a lot more accessible and easier to configure and mantain. It seems more resonsive and has a plethora of new features.
EXIF data is displayed with images, it has a crisper look and the layouts are easier to manage.
Go ahead, take a look at the new gallery.
