Future Labs has released a very handy application that will cut those bloody tourists from your holiday snaps called Snapmania.

Snapmania is the ultimate online photo manager. Your photos are securely saved, easily edited, efficiently organized with no limitation from where they can be accessed or when. It delivers everything you need and might wish and requires no software installation (if your grandmother has a computer, she can use snapmania!)
Try it. You will like it. You will find it to be as practical as it is elegant. But beware, once tried, you won't want to give it up again.

Don't worry now guys, it will also remove your mother in law without a trace.
