Wow, you got my theme gallery plugin to work. Everyone I knew who tryed it couldn't get past the resize bug. As far as I knew, it only worked on my server. Sorry for not releasing v2, it was a huge rewrite. 10x better. It even supported multiple instances of it's self.
Some servers have GD2 installed incorrectly, or something like that.. who knows. As long as it works for you, i'm happy.
The second version is basicly finished.. I never wrote the installation for it. It doesn't support GD2 anymore.. It uses ImageMagick. I wanted to get it to work with both before I released it, but I lost interest.
I'll look around to see if I can pull up an old db backup Maybe i'll through together an installation script.
