I was prompted by a friend to look into the possibility of Piclens earlier today. I was so impressed with how it worked, that I went ahead an implemented it in our photo galleries.
It effectively is able to create a full-screen slideshow of any of the Travellerspoint galleries. You can either view them directly in the browser or if you install their plugin, you can view the photos in a kick-ass 3D view.
Anyway, it's all there in the galleries to play with now. Relatively untested across browsers, so there may be some hiccups, but I was too excited to hold off. Hehe.
