PyWebGal is a WebGallery generator written in Python. It should be easily portable to any platform Python can be run. It is a plugin-based application, this means anyone can extend it's functionality by writind a simple Python classes. If you need some more information on how to do it - look into the Documentation.
It's main goal is to allow easily creation of multiple galleries from your folders (or directories) on the disk.
