But it is not specific to FB. It is specific to iPhone Panoramic photos, not to Panoramic Photos per se, that are loaded onto FB. As I said earlier, if I copy the visible image of an iPhone Panoramic Photo into Paint & save as a Jpeg with same dimensions as the iPhone Panoramic Photo, FB displays it as a wide flat image. But the other information about the photo is not present e.g. time, date, location & 'camera' on that Paint image. So, there is something encoded into the file by the iPhone that takes the Panoramic Photo, not simply that it is a Panoramic Jpeg image. As I said, I regularly create Panoramic images by sticking Jpegs together with Photoshop & they are always loaded by FB as a wide flat image not as a 360 image.
