Ideally the mezuzah should go on the side as one enters which would be on the right (yemin haknisah) since the front door is behind the photographer, but there is no full doorpost omn that side. chashivus is not really a factor here because both rooms are essentially the same and part of the kitchen.
So practically the mezuzah was put up on the other side. Is this correct? Should it be changed, and if so, how or even taken off all together?
