I don't remember all the details to Saw 3 but this is what I see.
The man who's daughter is kidnapped...anyway, I think the woman in the chair in the picture is the woman he was cheating on his wife with.
And Jigsaw is dead but made an instructional video for the father to find his daughter.
Ding, ding.
No wait scratch that. The woman in the chair is the blonde woman who appeared to be Jigsaw's girlfriend in Saw 3 during those flashbacks.
