As you may know from last posting, Google has just released Web Picasa Album optimized for S60. Recently, I created a S60 Widget for Picasa Web Album. What does this widget do? It basically adds a new icon on your main menu so that you can launch Picasa Web Album easier. As simple as that.
You can only use it for devices that are compatible with S60 Widget, such as N78 and N95. See here for the list of supported devices.
