Picasa 3.9 Web Albums

The latest version of Google's free photo editor introduces brilliant new features, including photo effects and filters such as HDR-ish, Sixties, Boost, Cinemascope, Focal Zoom and Polaroid. You can compare photos side by side - the original with an edited version, for example. There's also support for the new Google-developed WebP image format, and updated RAW support for pictures from newer cameras.
