This is a small program to download Picasa photo albums. It is written in python, with a PyGtk graphical interface.
If you run PycasaDownload, it will show you a little window where you can input a username (with or without the @gmail.com), for example: jsmith@gmail.com, and update the album list. Then you will be able to choose one album from the list showing album title (number of images), and download it. The images will be saved with their original name in a directory named <username - album title> in the current path.
Version 0.1 is available here. We are working on release 0.2, very soon.
