[ale] Bulk jpg Thumbnail production from 137000 jp2 files??

[Pete Hardie]

shell script, not necessarily error free:

for i in `ls *.jp2'
do
    file=`basename $i`
    suffix='suffix'
    convert $i <options> $file.$suffix
done

man basename for all the fun options - it can get you the path, a part
before the '.', a part after the '.', etc
