Save to gallery now works, but it also saves the image to the gallery if you select a photo from the gallery, which duplicates the image in the gallery.

Additionally the Error descripted in the original bug report is still there "Main Thread Checker: UI API called on a background thread". Which leads to long loading times when opening the camera.

I've checked and there is no code for saveToGallery on iOS, so that explains why it doesn't work.
