One way would be to use a gradient pigment_map to restrict the
image_mapped portion to the front.
pigment_map {gradient Dir
[0 ImageMapPigment]
[0 ImageMapPigment]
[0 NoImageMapPigment]
[0 NoImageMapPigment]
}
Or do something similar using layered textures to layer the image_map on
the base texture. That could be more difficult, though...
If you aren't committed to using an image_map, and are using MegaPOV,
those designs should be fairly easy to duplicate with the object pattern.
