Most definitely. Yes. Now, the bulk of a JPEG files consists of tagged
chunks. It's just a matter of inserting a properly formatted comment
chunk, pretty much right after the start of the JPEG file. I'll look
into it later.

If you can do it from Applescript, than it must be possible to do it rom
MacPerl with AppleEvents. Of course, then, you may forget about
cross-platform development.
You might check out Image::Magick. It's a free image manipulation
program with a scripting interface, including through a Perl module. You
can play with it online, through its website, at
<http://www.imagemagick.org/cristy/MagickStudio/scripts/MagickStudio.cgi>.
There are both standard source (= Unix) and Windows distributions. I
doubt if there's a Mac port, yet. I can't check, the server of
containing <http://pudge.net/mmp/>, the MacPerl Module Porters page,
hasn't been responding for hours.
Leonard Rosenthol has been working on an AppleScriptable Mac version of
ImageMagick the program, see <http://www.lazerware.com/imagemagick/>, so
it eventually might still happen.
And, oh yeah: the image quality produced by ImageMagick itself is of
professional quality, it's at least as good as Photoshop.
