Set a Watermark to be applied to photos.
A Few Things I've Noticed Upon Uploading ;
A. Scirra is not a fan of full screen + file choosing.
B. Sometimes when you load your logo it will take up the full screen and seem like it's not working, simply resize it with the slider bar.
C. In Editor it let you view the photos as soon as they downloaded, which was nice because it gives a chance to review, and share to fb insta etc. through your phone. As the app is hosted on a site it doesn't seem to be functioning at 100%, however there may be a future standalone edition you can download straight to your phone if it is wanted.
