Because you have Australia mode turned on
But seriously, no idea I don’t have that issue on my end and I haven’t heard of it before this either.
DRAT!
Some phones take pictures upside down and add a note “when displaying this picture, flip it”. If an app doesn’t support this feature, it may cause this issue.
What exactly are you doing? Are you posting image files, or posting directly from an app grabbing pictures from your camera live? What app? What operating system?
Both posting and browsing. I’ve seen it a handful of times.
Are you using Safari?
Probably ignoring/stripping EXIF rotation data and presenting it in its original orientation
If that’s why, good. Lol that was a concern I had with posting any pictures on here.
I haven’t seen any being flipped upside down, but portrait mode turned to landscape seems to happen here and there. Maybe some issue with device orientation from the metadata?
