Reworking the gallery

After a long day, I've finally finished changing to a different gallery system. There were some issues with the one I previously used, and I'd been dreading the task of changing to a different system. But today I finally did! This included deleting all old images, and adding all those images using the new image module I'm using. Unfortately, this means that comments on pictures were lost. I might be able to reproduce them somewhere in the future, but right now it'd just be too time-consuming.
