Well, this one and aquaria central along with aquatic-photography are all part of monster aquaria network and use the same forum software. What doesn't work on one isn't going to work on the other.
I've tried playing with the code from photobucket and no matter what I try (not just copying and pasting, but actually writing code) doesn't work. I think that the forum software used here doesn't know how to process photobucket's code for making the slideshow play. I'll keep working on it and see what I can come up with.
