If I understand what you want to do, it's possible to do it with
convert from imagemagick (http://www.imagemagick.org).  It basically
lets you draw text or shapes on top of an image (and works with a
few dozen image formats, including ps, so you could do it with the
original photos).  I believe imagemagick also comes with c libraries
and/or perl modules with similar functionality.

I'm sure it's also possible to edit the ps file, but I don't know how
to do that.
