I know 'color_map' 'image_map' 'pigment_map' are only names but according to
'_map' appendix IIRC only image_ and bump_ can't be declared. When you use the
same image as bump_map then it allocates space for image twice. So ideal
situation could be something like:.

#local Image=image{png "imagefile.png"}
#local P=pigment{image_map{image{P} image_modifiers}}
#local N=normal{bump_map{image{I} bump_modifiers}}
