It expects a scalar float value instead of the color the pigment image 
gives. Try "function {ImageFunction(x, y, z).gray}"

I thought there was another keyword that used the same algorithm the 
height field object uses to get a float value from a color, but I guess 
it didn't make it into the final release. The ".gray" method should be 
close enough for most purposes though.
