IIRC, you can download the necessary code to run Fotowoosh or whatever they originally called it yourself, but who wants to do that? Now (I discover, thanks to OUseful) they have made it available through Facebook. I hope I'm not breaking any rules that I've not read about by embedding here an instance that I've made through that site. Here you go, anyway, a view of the Getty Museum with LA in the background. It's evidently not the perfect sort of photo for the job but you get the idea.
