BMP is not supossed to be supported by ANY browser. It's not part of the W3C specifications. Of course all browsers are supposed to support PNG as of 3-4 years ago (when 4.0 came out and GIF became a proprietary and sue-able offense to use.) and that's not quite happened either... You get splotchy somewhat random results using PNGs.

Truth has no value without backing by unfounded belief.
