Don't worry - we don't crop the photos you upload. What you shot is what we print!
On the second screen of the publishing process, entitled 'Place' (below) we show a square grid of photos, so that you may see what photos will appear on opposing pages of the magazines.
These are just thumbnails, not representative of what's being printed. This is exactly like Apple's Photo's app shows photos.
The full photos will be printed on those pages. You can press and drag these square thumbnails to re-arrange which pages have which photos on them.
