Yeah, I phrased myself poorly. Most of the proprietary file formats, though, are for use in somewhat specialized fields, such as game creation, etc. Jpeg is so common, it seems kind of like trying to copyright the letter A. (Darn, shouldn't have mentioned that. I'm sure someone will try!) BTW, I wasn't aware of the GIF issues others mentioned. GIF really isn't capable of doing even web based continuous tone images. Even with an optimized pallet, the color gamut is still pretty weak and the file size is monstrous to get a decent image up.
