How can I load a .bmp or .jpg image and set it as background for OpenGL viewport?

this you can do the following way:
- load your background image as a texture
- before rendering a frame, change to orthographic projection and render a quad that is exactly screen sized at a distance from the viewer that is nearly the far plane of the viewport
- then, change to normal perspective mode again, and render the scene.
