I accidentally have a picture posted that is rotated. How do I delete it and reupload it?

It was off your screen, right? Why not just use Gyazo to screenshot it so it wouldn’t come out rotated, and so the quality wouldn’t be as bad?

Looks like you took a screenshot...with your phone...of a clothed Fortnite character...and posted it. So many things wrong with this. Just...don't do that...it would be deleted even if you fixed the rotation.
