MyPublisher has released an iPhoto plugin that allows users to break from Apple's integrated photobook ordering system and order the MyPublisher product. The plug in doesn't replace the iPhoto layout functionality, but takes users to the MyPublisher website when they click on the "Buy Book" button.
Also, the first 5,000 users who responded got a coupon for a free 20-page hardcover book. The company will, however, send you a coupon for a free book with the purchase of a book from MyPublisher.
