Previously we've asked the simple question; "Can you name the Doctor Who episode from just one photo?" The answer was generally, "yes."

However, we only gave you the stories of Tennant, Smith and Eccleston to choose from – and that was obviously too easy.

So we've devised another quiz which includes 50 years of adventures in space and time. Are you equal to it now that the likes of Tom Baker, Jon Pertwee and Peter Davison are in the mix?

Good luck...
