I suspect that this would be a difficult theme to implement and not just for
non-*ist D owners.
Indeed.. I'm nowhere near that many yet (bows head in shame :)
Also, chances are half the people who even are will not have kept a given shot, could easily be one deleted in-camera, or later.
How about the highest prime numbered shot that you still have from your istD :)
