Hi Bruce,
Thank you for your answer.
 What I am thinking about is that after the picture is modified by a
designer so that it is suitable for a tactile that it could be saved   to
a file type that is specific to tactiles and that any embosser would
recognize it and be able to emboss it.  I understand that the producers of
the embossers would have to decide to support this file type. Right now
the embossers fall into, I think, 3 groups. One that can only emboss
Braille, another that can emboss braille and has a graphic mode ( dots
closer together) and the Viewplus embossers which have, I believe the
closest dot resolution. 
It would be working towards a type of standard. And it could be attached
to a picture file as a possibility to open just as one has alternative
You wrote that you "wouldn't expect it to happen soon", where would such
things be decided?
