@kaysavetz CoSo removes the metadata from the image to preserve your anonymity but in the process it can remove data that says which way to orient the image. Basically your image is stored sideways but it has an instruction in it to tell viewers to rotate it, and CoSo takes that instruction out.
To fix it, generally all you need to do is open the image in any image editor, make sure it’s rotated how you want, and save it.
