It seems ankward that I have to load an image_map twice into memory if I
want to use 2 kinds of map_types (spherical, cylindrical etc.) with the same
image... Is there are way around that? Maybe a function?

#declare basePig = pigment {image_map {...}}

#declare sphPig = pigment {basePig warp {spherical}}
#declare cylPig = pigment {basePig warp {cylindrical}}
#declare torPig = pigment {basePig warp {toroidal}}

I'm pretty certain POV copies image data by reference, similarly to how 
meshes handle geometry data. Even if it doesn't, this will avoid reading 
and decoding the file for every use and makes it easier to make 
changes...you only need to change the image name in one place.

Thanks! Yes of course, a warp!  Although it's slower to render....

Thanks,
