i tried to change my picture,but it says it's working but, really it's not! On my account the picture is supposed to be a peace sign!

Don't worry, it is a peace sign now - quite a cool pic I have to say. I've had the same thing before, I changed my pic. but it didn't change for me straight away.

You can try signing out then in again, or you might just have to wait a couple of days. But it definitely has changed to a peace sign now ;)

cool thanks! :)
