My daughter's preschool uses Teddy Bear Portraits. They come one day to take the photos and do 3 different poses. Then they come back a week or so later with the 3 different poses printed out and the parents can just buy the ones they want. There is also a free gift for each child (really the parents) that goes along with it -- one year it was a canvas bag with the different poses printed on it; another year was a mouse pad with one of the poses printed.
