Gallery.py makes picture galleries consisting of an index page with thumbnails linking to pages with resized pictures. The picture pages include a navigation bar and a simple GUI and picture comments saved in an XML file. Date information is extracted from the pictures if available. Possible comments include 'date', 'where', 'who', and 'what'. The script is very well suited for cron operation on a hierarchy of directories using the --recursive option.
