Are you doing this from a phone or computer. When its from your computer, just save it somewhere-flip it-save it again and post it. Ifin its from your phone, remember to take pictures with your phone SIDEWAYS not upright like you are dialing.
I'm doing it from my phone. ..and have mastered taking all my phone pictures sideways for future posting . " Learned the hard way ! " But on this one ,it's somebody else's sideways picture that I downloaded and rotated, then tried to repost upright, but failure ! Oh well I guess that there is just no way of righting one from a phone.
