The new timeline includes a big photo as the header alongside the small profile photo we always had. FB suggests you set up the timeline and choose your photos because when time runs out THEY will do it automatically. How will they select the photo? The main photo is publicly visible, as far as I can tell that can't be changed. Yet facebook say that switching to timeline will not change the privacy settings of anything you already have there. Surely this is contradictory? Any photo which is auto-selected for the header will automatically become visible to the public? What if all your photos are friends only or even more restricted?
