I've changed over from Gallery to Zenphoto for managing our pictures. Part of the reason is because Gallery, while being an all-around awesome program for managing multimedia, is way too heavy for what I need for web photo management. Zenphoto is absolutely what I've been looking for in a web photo management software. It's light, takes up little space, and is quick. Plus, the editing features are really nice, and it supports ratings. Yes, now you can rate our photos. How cool is that?
Oh, and the beauty of it all is all of the links to the old photos are broken again. :) Yay!
