Have you heard of Hotprints??

It is a neat site where you can make a photo book once a  month for free.  They don't even charge shipping.  If you are like me and take a million pictures, it is a cool way to share them.  The book is similar to an Elementary school yearbook.  They put ads in the book, but not on the pages, they are inserts that you can take out.  This is how they are able to do it for free.  The website is http://www.hotprints.com/
