Chosen answer: It's metioned in the filmakers' commentary that in every Final Destination movie everyone has a premonition (Of course), well it's also mentioned by the director, James Wong, that if death wants to kill them why give them the premonition in the first place? Well he believes that there is some other force out there trying to prevent death from killing these teenagers. That's where the premonitions come in including the signs therefore, Wendy's pictures are helping signs like voices or visions from other movies. It's just the whole "giving signs" thing is portrayed differently in this movie.
