The photos you have uploaded to Zno are not available to download off the site.
You are able to 'share' your book with your friends, family, or clients. When you click on the 'Share' button, which you can find on the My Projects page or in the design software (both pictured below), you can copy the preview url and email it to them for viewing. The preview url is a brand free page for them to review your photobook in a lower resolution.
