# thumbnailer.py
#
# A quick and dirty script to walk a directory tree, find jpg's,
# make a thumbnail, and make a 800x600 version. Also makes an
# HTML file to show all of the thumbnails (with links to the
# 800x600 version). Designed to take the high quality pics
# from digital camera and produce a web friendly version gallery.
