Rnvinc is correct .... if you take a cellphone pic with the phone held upright (portrait mode), it will sometimes post laying on its left side (landscape mode). If you take the pic with the top of the phone to your left, the pic will post upside down. So, if you take the pic with the top of the phone pointing to your right, it should post in the upright position.

How in the world you managed to get a pic to be rotated 1/4 turn to the right is beyond me ... unless you took the pic with the phone upside down
