I'm playing with the effect using the scripts from Lightbox 2
http://www.huddletogether.com/projects/lightbox2/basically need to figure out where the template is for viewing the gallery posts and edit that template up. so when you click on the image in the post it pops up with a different css tag is all.
Pretty simple really. and would help my gallery look much better...
I was able to use this hack for my phpbb2 forums...
