Hello all. Our school is designing a yearbook with the book feature in iPhoto 06 and 08. The problem is that iPhoto saves the book in the application itself, but we cant find the file in finder so that we can transfer the book to other users so they can modify it. We can save the book as a .pdf, but iphoto cant open a pdf and modify. So for now, we can only use one computer at a time to do the book, which is time consuming and frustrating. All the photos are in /home/pictures/iphoto library. But where does iphoto save the books? Thanks.
