Image browser seems to like ImageApi ImageMagic or GD2 command line interfaces enabled

I tried installing Image Browser and got error -- "There are no image toolkit modules enabled ..." I had enabled the required ImageApi but not a specific GD2 or ImageMagick one. It would be nice to note that you must enable one of those also. However, on one site i managed to enable it without one of those modules enabled and it worked pretty good although i think i may have been causing seemingly radom errors. Anyway, thanks for a great module.
