download_picasa_album.sh is a simple little shell script that downloads entire photo albums from Picasa Web. Just give it the album’s RSS feed, and it will parse the feed, extract the links to the full-size pictures, and download them one by one. For example:

$ ./download_picasa_album.sh 'http://picasaweb.google.com/...&alt=rss'
    % Total    % Received % Xferd   Speed   Time    Time  
                                   Upload   Total   Spent 
  100 74442    0 74442    0     0      0 --:--:--  0:00:03
  ...

This script is dirt simple. If you’re looking for something robust and full-featured, you probably want an RSS reader that supports enclosures or a dedicated web photo downloader instead. Personally, I have a small brain, so tiny shell scripts like this are just right for me.

download_picasa_album.sh should work on most *nix-based systems. It uses curl, grep, sed, and xargs, which should come with your distribution.
