Picasa FTL?

Picasa was less useful than I had hoped. It seemed to merely be a means of creating a slideshow by downloading a few photos and simply organizing them like a PowerPoint. I did like the game that was incorporated into the website however, where you had to guess where a picture was taken. I WOULD like to incorporate something like this into my classroom, possibly finding specific Mathematical places of importance and testing their Geography as a cross-curricular activity.
