I was looking back through the screencaps of the scene with Miles and Mrs. Gardner. When he goes upstairs, they focus on the pictures on the wall. The picture of the boy is in a large wooden frame. Then Miles goes upstairs, does his thing, and comes back down. They focus again on the same picture, but this time it is in a metal frame. It is the same picture just a different frame.

Is this a continuity error or is it something Miles somehow changed? I really doubt they would make such a blatant continuity error in a scene they put so much focus on, though, so what are your theories on this?
