Try a glass scraper as used for cleaning ceramic hobs.

Hi
I've moved into a new house and in the main bathroom, the white tiles have a picture stuck on to them to create a patterned effect. I think it will peel off but am unable to even pick at it with my nails. Does anyone have experience with how to get it off?
