Colin's camera?

No: HPFGUIDX 90131

I know I'm taking this back a few books, and that this has probably 
been mentioned before, but how does Colin's camera work in Hogwarts? 
No electrical things are supposed to work there, and Colin had an 
electrical, Muggle camera. A friend proposed to charm his pictures 
into moving, so I'm guessing that the camera would have to be a 
Muggle one. I've always thought this was a contradiction, but never 
really bothered to post it. Maybe it's just a Flint. Any suggestions?
