You 
can change the photo book type and covers from one to another of the same size. The option to do that is in the left menu of the book builder screen. Just click the menu icon to see the available types of books. Click one to change the book. This will make a copy of the book with the upgraded book type while a copy of the original book project with the original type is saved to your Projects page.
Once the copy is made, the new book project is what you will see in work space, and since it is independent, any edits to the new book are not updated in the original book project.
Note: Make sure to review each page of the upgraded book (and/or the original book) before ordering.
Limitations
- Currently available only for books of the same size.
- Depending on the type of book you are creating, you may see fewer or no other book types.
