I can confirm what Happy Mom said. In fact we did the "shutterfly" book by downloading both photopass CD pictures as well as ones we took. Photopass wanted $90 for the book, Shutterfly was $45.
The only difference was the pages did not have the copyrighted Disney borders with characters and logos. The way we got around this was before you order the CD, embellish the pictures with the logos and borders on photopass. It turned out so nice and had alot of fun doing it.
