Flag lets users print 20 museum quality photos a month for free, thanks to small ads placed on the back of each print.
Users downloading the Flag app simply allow it to access their smartphone photos, pick the ones they want printed and click print. Flag then sends the bundle of 4×6″ photos in the mail, printed at museum quality on 220 gram photo paper. Instead of a white space, Flag places ads on the back, which enable users to get up to 20 prints a month for nothing.
As well as the ads, the back of each image also contains a custom caption written by the photographer, and a QR code that contains the metadata of the photo and also allows users to easily order a reprint or share it online. Customers have a choice of rounded corners and laser-cut edges, as well as being able to blow up a single image by printing it across 20 pieces of 4×6″ paper. The photo can also be sent to a friend as a postcard. read more about Flag
