Thumbzilla Description:

Thumbzilla allows you to create thumbnails from images (JPG and GIF) and movies (MPG, AVI, QT etc.). The user decides what size (width or height) to proportionally scale the thumbnail JPG, the source directory and files and the destination directory. The batch process then creates the thumnails specified without user intervention. However, an option for movie frame selection is provided. If turned on, the user is shown each movie and can choose which frame to use for the thumbnail. Otherwise, frame one is used.
