You can use SDL to easily load BMP (SDL_loadBMP(char *)), source code of the function is available on www.libsdl.org

It wasn’t being answered very well, or you weren’t reading the answers very well? One person provided a link directly to a BMP loading routine for you. Ah well…

A couple notes about SDL, I could be wrong, but I think that the image loading stuff is actually part of the SDL_image library, so you’ll need that as well. Also since you had problems with this with glAux, I should mention that you will also need to link in the SDL libraries, the same way I replied on how to do it for glAux.

or…
you could look up the format of a .bmp file on microsofts’ site and then read your file in appropriately.
(you probably did something similar if you got textures working using .raw files)
