I did this sort of thing regularly but with animated meshes made in Poser.
Several winters ago. Tim Cook IIRC, made a TV where the image files were 
stored in a df3. The frames were selected by intersecting the df3 with a 
thin box. The result was monochromatic. But if you used jr's tga2df3 to 
create the df3 (actually 3 df3s one for each RGB channel.). Then you can 
have the image in colour, if you use 3 media in the material. *Not* that 
I am suggesting Phil uses that method. That would just be showing off. ;)


My own particular set-up would be...

I'll just point out, again. That the BITMAP_TYPE should not be included 
in the concat function. When I tried that earlier, Pov threw a wobbly 
and complained that the first letter of the file path was an undeclared 
variable "C". Also #debug would not output the result of: 
image_map{concat("png  ","my_image",str(frame_number,-4,0),".png")
That made me feel that I was losing my marbles for a while.
