Re: Title Page in Photo Book
I know this is an old thread, but I needed the answer to the question, myself and I finally had to go to Live Chat. I'm putting this answer here for anyone who needs it in the future and is getting discouraged. (This thread shows up pretty high on the list if you try to google the problem.) The answer is that you change the title (and author) information by going to the File menu and choosing Edit Title and Author(s). This changes the title on the title page from My Photo Book to whatever you want.
