You should get pics to the proper orientation before you upload and post. Just a few clicks to rotate 90 deg (I used MS Paint to do it). It's not your software or browser. Probably your phone is set to "help" you by trying to detect which way is up when you take the picture, then auto orient when displayed. I always try to take pics in landscape rather than portrait (would have stopped the sides of your beautiful car from being cut off).

Hope this helps.
