Joe Walnes is a great open source developer who works on mobile fun in the Google London office. He just released a new iPhone interface for Picasa:

I had a look around some websites and I really liked how they looked on the iPhone. I could get to everything I needed. I went to picasaweb.google.com but it didn’t quite feel right. It was using some very cool AJAXy features, but these were designed with a desktop web-browsing experience in mind. So the next day I had a go at creating a new interface for Picasa Web, designed for the iPhone.

Today, I’m happy to tell you that we’ve just released this new iPhone interface for Picasa. After you go to Picasa on your iPhone and log in, you can quickly see all your albums that you’ve uploaded to Picasa Web. If you click on any of the albums, you can get a full view of your picture with comments from your friends. Or you can click on Slideshow, sit back and watch the pictures scroll. You can also search for photos in your album or through community photos. Finally, with one of my favorite features, you can view your friends’ albums through favorites.
