Bump Map Tutorial
"What is a Bump Map?A bump map is a way of superimposing one image onto another. The bump mapped image will appear to be raised (or recessed if inverted), with the image you are bump mapping it with."
The tutorial is inside.... The purpose of this sample bump I made and posted above is to get the brain to stand off the page a bit; give it a little depth.
