Thanks to everyone that replied.  
The "convert" tool from ImageMagick works great!!!

The following script shrinks a list of .jpg's to 18% of original size,
adding an "s" to the new filename.  i.e. "pic001.jpg" -> "pic001s.jpg"


#!/bin/sh
for f 
do
        n=`echo $f | sed -e 's/.jpg/s.jpg/'`
        if [ -f "$n" ]; then
                echo "overwrite $n? (y/n)"
                read ans
                [ "$ans" = "y" ] || continue
        fi
        echo "creating:  $n"
        convert -geometry 18% "$f" "$n"
done
