True, but no software exists (whether GnuPG or PGP) to do this today.
In both cases you need to select the key in question, and then view
the photo. It's sort of a backwards way to select a key as normally
the user ID is used to get to the key. I can see photos being used
more as a "select a key, then look at the photo to confirm it's the
right one" rather than a "encrypt to that photo".
It would be interesting to see a GUI that did what you suggest. It
could be very helpful to people who were not particularly

I quite agree. I think that would be a wonderful keyserver
enhancement. Since the photo is actually a straight JPEG with some
OpenPGP header bytes that can be ignored, it should be fairly
straightforward for a keyserver to feed the JPEG data back to the

I responded a few days ago. Didn't you see it?
