I know that the "convert" utility in ImageMagick will do it, but I
can't remember the exact commands to do it (I don't do it very often).
 If you want to resize a whole directory of JPEGS, I think you're
going to want to do something like:

mkdir new_jpegs
for file in *.jpg; do convert -resize <new width>x<new height> $file
new_jpegs/$file; done

(Everything between "for" and "done" should be on one line, but it
will probably be broken up when I send it.)


If that doesn't work, read the man page for convert.  It's terse, but
I'm sure you'll find the correct options there.
