Gallery2 backport for Sarge
Gallery2 is a web-based photo album with multiple user support. It provides users with the ability to create and maintain their own albums via an intuitive web interface. Photo management includes automatic thumbnail creation, image resizing, rotation, ordering, captioning, searching and more. Albums can have read, write and caption permissions per individual authenticated user for an additional level of privacy.
Gallery2 (G2) has been redesigned from the ground up and is database driven. Two years of design and development have gone into G2. It has customizable themes and layouts using XHTML compliant templates which make it much easier for you to personalize your G2 install. G2 is modularized and features can be enabled and disabled separately for maximum control.
