Google finally released their photo organisation software, Picasa for Linux. It’s a free download, and uses Wine so it’s not a truely native port. I’m going to try it out now and will update this post later with my thoughts and impressions!

Basically, do what you like with those images but always credit Donncha Ó Caoimh as the author and link here. You'll also have to license the photo under the same license.
