You might have tried your hand at making one of the fangly 360 images that Facebook not supports but ended up with just and image instead of the expected 360 image experience. Well, the most likely issue is that during editing the image, the Exif information for the image got all screwy and Facebook didn’t recognize it as a 360. This free tool for Windows and Mac can add the required infor back into the image. It’s FREE and easy as hell to use.
