Since blurb is not a specialist photo printer why don't you try one of the online picture printers who now all seem to produce photo books in various sizes and on various paper thickness. In the UK we have photobox and Jessops (major photographic retailer) who have started doing it too. And then there are dozens of wedding photo printing services producing books but maybe more expensively. Why home in on blurb who are really about publishing the written word more than photography. Unless of course it's the online sales of the book you really want.
