Remember #CosoNewbies: If you're posting pics from your phone, either take the pictures in landscape, or make a small edit, save, and then upload. Otherwise, they'll load sideways. This is yet another security feature built into CoSo so that no one can track you by your picture's metadata.
@jazzdetective It doesn't, it just posts correctly if you take it in landscape. Again, this is only for phones, either Android or iPhone. This is NOT an issue with a computer.
