 I wrote a Korn shell script called "jpeg-thumb-dir" to do this. You can
find it here:

http://www.giantfoo.org/~johan/tech/source/its-alive.html

It requires the "djpeg" and "cjpeg" programs.  It work on directories, but
does not yet have a recursive mode.  (E.g. it will do one whole directory
of images.).

It's been tested on NetBSD and Solaris.
