I am using the first image as a source for eval_pigment which I use
to generate the second 'image' of colored spheres.  Except it seems to
be in grayscale. Any ideas? The relevant code:

#declare Source =
         pigment {
           image_pattern {
             png "04.png"
           }
         }

#local a=0;#while (a<1)
         #local b=0;#while (b<1)
                 sphere { <a,b,0>, .00325
                         pigment { rgb eval_pigment (Source, <a,b,0>)}
                 }
         #local b=b+.01;#end
#local a=a+.01;#end

Hmm. Try to replace image_pattern with image_map, since a pattern is always
grayscale.. (btw I didn't know there was an image_pattern keyword)
