copying photos from an I phone 4s that is not on your itunes

I bought a phone off E bay that had a broken screen. The person that I bought it off has asked me if I can fix it could they have the photos it had an app locker on it and have disabled that but they cannot remember what the I tunes password was so cannot access the camera role folder. Can anybody help. I need to wipe the phone as its a Christmas gift and don't want to get rid of the photos as they are all of the blokes family.
