Picasa have two aplications:
Picasa web: You can see and share photos in Internet and is free. Only need a Picasa account.
Editor of Picasa's Photos : You need download the program. Don't need an account of Picasa for download the aplication. Is like a Photoshop but it's free and has limited functionality.
It's totally free and very easy to use.
It’s available in all languages.
The third image is of my Picasa account.
