I am using the Phantom 4 pro plus (crystal sky). How can I post 360 photos directly to Facebook without just posting a link to the Skypixel site?? I would also like to know how to download a stitched 360 photo to the sd card.
Anyone have an idea how to do these things?

I dont think you can share a 360 photo directly to Facebook. Only Skypixel. If you do click share to Facebook, only the image is added to facebook . ie. without the poroper meta data, so facebook only displays a normal still image. What I generally do is use software to stitch the photos offline. You get a better higher resolution photo plus yo can colour correct it etc. The software adds all the proper meta tags for Facebook and 360 sharing websites. I use PanoramaStudio 3 but there are free software to do it.
