Lionsgate has released the first official photo from SAW 4, which can be seen after the jump.

Saw 4

I'm not quite sure what is going on in this trap, but there does appear to be a timer on the wall counting down to something. I would guess that the numbers are minutes, which means there is about an hour and a half left. And what is with the pig mask? It appears to be a woman in the chair. The photos on the wall show a guy and a girl, while the writing above says "See What I See". Could the guy in the photos be the new jigsaw?
