How do I know if my photos have good enough resolution for print?
We recommend using photos with a minimum size of 900px for collages and more for a single photo per page.
We have a photo quality indicator that is turned off by default, but you can turn it on this way: In the book preview, click the Edit button at the bottom of the page, then click Show photos quality. You will then see small green, yellow and red indicators in the top right corner of each photo in your book. Green means good quality, yellow means good, and red means you should hide or replace the photo. A photo with a red indicator means the DPI is low and the print result may be pixelated.
For best results, photos should be at least 10 megapixels.
