Look at the shape of the 'window'.

Now look at the shape of the door panel.

There is literally no way that 'window' could ever roll down and fit into that door panel.

This is simple and obvious visual geometry, slide top shape (window) down into bottom shape (door panel), it simply cannot fit.

Therefore this is not a real photo, as the window arrangement is physically impossible.

Exactly

Yeah, OP's photo is missing that triangle plastic piece in the back corner, making it a fake image. Without that plastic bit, with the window filling up the whole door frame, it cannot possibly roll down. It simply cannot fit into the door frame (OP's image can't I mean).

Edit: Also, OP's image doesn't even have a window frame.
