It's unclear what this new process means for Flickr's partnership with HP's Snapfish, which was the source for Flickr photo books. It's 50 cents per page after that, according to Yahoo. The books can run from 20 to 240 pages, and they'll start at $35 for a 20-page book. We are working on bringing you Flickr Photo Books soon,' the blog says. Users outside the continental US will have to wait longer. Starting next week, US users will actually be able to purchase the books, which Flickr said are printed on premium photo paper. Users can also go in manually and make tweaks, delete images, or reorder the pages. That includes simple layouts, placement of one photo per page, and tools that will 'analyze, crop, position, and rearrange your photos to look their best,' the Flickr blog reads. Flickr is promising that the bound books are laid out to optimally showcase a photographer's work. Users need only to click the book icon on any of their sets, according to Flickr, and the site will automatically generate a photo book. Flickr is adding a one-click photo book feature for its users, Yahoo's photo-sharing site announced Tuesday.
