Yahoo has decided to add a new revenue stream to Flickr with the launch of Photo Books, which let users order books comprised of their photos.

“Pick your favorite photo set, click on the Photo Book icon, and we’ll automatically turn it into a beautiful book for you,” says Flickr VP Tom Hughes. “In almost no time, you can turn your photos into something memorable, that we’ll send it right to your doorstep (or to a lucky friend or family member.)”

“Our focus with Flickr Photo Books is to make it simple and intuitive to create a book that always looks great and is beautifully finished,” he adds. “From the handpicked full-bleed layouts, to the heavy stock photo Lustre paper and the image-based cover with matching dust jacket, we know you’re going to love your books.”

And obviously, this comes just in time for the holidays.

It will cost you $34.95 for an 11″ x 8.5″ glossy hardcover book with matching glossy dust jacket. That’s for 20 pages. Beyond that it’s $0.50 per page. You can only go up to 100 pages.
