It is possible to rotate a picture on an iPhone to the desired degree angle.

1. Go to your pictures in question

2. Tap “edit” on the bottom menu. If the menu is not there, simply tap the picture once to bring it up.

3. Tap the square button with little arrows around it

4. Ignore the compass-like ability to rotate the picture at this point, hit the small square with the one arrow in a quarter-circle pointing counter clockwise in the bottom left quarter of your screen until you’ve got your picture rotated to the desired position

5. Hit “done” and then post as you would any other picture from your phone.
