Another note for you Lurker,
When I was going over some of the packs I had downloaded, I found some images that were much larger than they should have been.
When I edited them I found that some of the jpgs were actually gifs that were not converted properly.
They had all the frames still in them so I chose some of the frames that were different and extracted them to their own jpg.
You may want to check for that kind of thing when going over the old packs.
Also, If anyone has suggestions for new image types, please post them here -
http://www.pinkpetal.org/index.php?topic=3433.0I can (and probably will) add just about anything that gets suggested.
It is just a matter of when I can get to it, but adding image types is very easy.
Incorporating them into the game to actually be used is a little more involved but at least they will be readable by the game.
