How can I put a BMP image in background???

I want to put a BMP Image in background, and make an animation in the foreground…
Is it possible and how???

I would suggest you you draw the bitmap as a texture on a quad. The quad has to cover the full screen. You have to disable writing to the z buffer while you draw it, this makes sure anything else overwrites it, regardless of its distance. Also disable lighting, fog and those stuff.
