Should work I guess. I use them all the time, with Poser figures in 
particular. Example:

#declare p_map13=pigment {image_map{jpeg "JamesHair1.jpg" gamma srgb 
interpolate 2 transmit all 0 filter all 0} }

I never used that wiki example though. I wonder if that is not 
specifically for GIF image formats only...?
