I just found this in my docs...

3.4.7.6.1 Specifying an Image Map
IMAGE_MAP:
  pigment {
    image_map {
      [BITMAP_TYPE] "bitmap[.ext]" [gamma GAMMA] [premultiplied BOOL]
 If the BITMAP_TYPE is not given, the same type is expected as the type set for
output.
I think this might be wrong. I think it should be '.ext' it's talking about.
What we(I) have to do is test it.

Have Fun!
