Pics upside down....IOS and Windows do not play well together. So you take a pic with your iPhone and post on website which most are windows based. IOS doesn’t tag that pic for orientation that windows recognizes. This may have been older iPhones, as I’m no expert. Work around....If you will hold your iPhone with the volume buttons pointing down toward earth and use one of the volume buttons as your shutter or in other words snap the pic with the volume button, your orientation will be correct when you post that picture. I haven’t ran into this problem with my iPhone 8.
