I know we'll get given a card and all the photos are linked to it, but then how do we get the photos printed out?
You have to order the prints from Disney or order the CD. I think you can buy both at the parks but I have never done that. I buy from the website www.DisneyPhotoPass.com
If you buy the cd you can order borders, logos & character signatures to the photo's aswell. You also 'own' the pictures so can have them printed out from the cd aswell.
