I don't know of any app that'll  let you do what you want. If you use
gnome, one option might be to display thumbs in nautilus and write a
little script using zenity to get a quick and easy box that will
display the output of the command to display the comment. You dump
that in your .gnome/nautilus-scripts (or some such place) and it
becomes available when you right-click an item in nautilus.

Right, since it would only read EXIF comments.

You might consider jumping to EXIF or IPTC at some point. Picasa2 now
writes captions and keywords as IPTC data so the info moves with the
file (http://picasa.google.com/features/features-edit.html). I can't
wait for linux apps like F-spot or maybe even Gqview to get this
functionality. What a nightmare to discover that all my photo tags in
F-spot were dependent on the db and weren't actually written in the
file itself! If anybody knows of an app that allows one to create/edit
IPTC tags I'm all ears.
