Ah shucks I think I used the wrong term. I meant "image map" not color map.
I have this awesome targa bit map that I got which is an aerial shot of my
terrain taken from a plane. I can colorize it in a paint program. Then I
want to move successive versions of it on top of my wireframe height map in
POV. The color map idea wont' work for this approach at all. I need to know
if I can move bit maps in and out.
