BTW, if you need the thumbnails to be a specific size (height or width and
retain the aspect ratio, consider this:
$ convert -resize x32      $i    $i.jpg

As usual, the convert man page (man convert) explains everything.
Call it a difference of style, but I prefer for options to come before filenames.
