Well, under Linux, I use a program called convert (part of the ImageMagicK
package), a command line utility commonly installed on Linux system (and very
likely available for MacOSX as well), in a simple looping shell script. It is
*possible* that the ImageMagicK package has been ported to MS-Windows, in
which case it would then be possible to create a BAT file to do this as well.

#!/bin/bash
mkdir qsize
for x in *.jpg; do
  convert $x -geometry 50%x50% qsize/$x
done

The above (BASH) script will convert every JPG file to 1/4 (1/2 as high by 1/2
as wide) of its original size and store the result in the subdirectory named
qsize.
