Got the test print yesterday. And it looks good. Still needs some work on the cover and layouts. But we're almost there.
The books are 20x20cm. Up to 160 pages. Up to 4 photos on single page. Thick paper. Nice print. Good colors. Nine different layouts, including full page print. Every photo has a date included. Custom covers can be added.
These are quite awesome. And a book with 365 photos in it can be made in 30s with our "Autofill" feature. But I'm sure noone will use it, since it's a lot of fun to make the book.
