Basicially, if you upload an image, then go back to the members page and see a broken image icon, something failed in the backend, and I may not be able to fix it manually. (I'm going through some now and manually creating the gifs.)

Well, I changed the backend to now try and convert the BMP files, and if it fails, it then runs it through a less efficient one, but it seems to get the job done. Should virtually elliminate any problems with legitimate files getting the broken image treatment. Now to get back to adding new features to the site again.
