I would also like to point out that I doesn't have to be an instruction that programs can use. It could be a DIRECT mode only thing something like:
GRPGET 0
To where it would tell you to select an images,warning you about selecting personal images and what not. Then it would paste the image to a graphic screen, in this case, 0 (Default top screen) Then you can just save it! I'd be happy with that.
