One and only one rule: the photograph should be squareFormat.
You can post as many photos as you want, 6x6 scans, cropped digital, etc. as long as they are SQUARE!
No, your photo will not be deleted if its size is 495x500px but PLEASE stop posting non-square format pictures, they will be deleted, even if they were taken with a square format camera and cropped!
Diptychs, triptychs of square photos are ok though.
