I do! my version 3.7.0.RC7.mevc10.sse.win323.7 will let you do this

plane{z,0 pigment{image_map{"Uimage.tga"}} finish{ambient 1}}

but not this :

#declare I_File="Uimage.pgm";

plane{z,0 pigment{image_map{I_File}} finish{ambient 1}}
             OR
#declare PigM=function{pigment{image_map{I_File once}}}
             OR
#declare PigM=function{pigment{image_pattern{I_File}}}

I'm comparing function to image_map height_fields. I needed the macro so I would
have to rewrite the file I'm using for each height_field.

My version 3.7 for my 64bit running on win10 Acts the same.

I can write the file string directly into both of the functions above, But I was
trying  not to do that.
