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

[Sparr]

To avoid having to wrestle with different tools to make lists of files
what I will often do in this situation is something like this:

find -type f -name "*.jp2" -exec convert {} -resize 14% {}.jpg \;

This will result in your thumbnails being named whatever.jp2.jpg which
is not a horrible naming schema to have.
