I chose an upgrade from the standard book paper for my softcover photo book, and used all the same images I had previously used with a slightly higher priced hardcover book of the same size at a print on demand book site which did NOT have a store option for selling. The book on the other site was easy to design, looked good, with no surprises... BUT the Blurb softcover book looks like a report in a folder, rather cheap and tacky looking! No blank front & back pages, and the paper quality is marginal.
The design software is not as easy to use as vista print, and I struggled with it. I did not find a simple way to standardize all the pages and fit my images consistently. Instead I ended up with different border widths throughout which looks terrible.
I will probably try elsewhere if I can't figure out how to apply a standard template to every page!
