This is odd, especially as the thumbnail orients them correctly, only to have them sideways when viewed. The regular photo viewer in nextcloud displays them correctly.
Here is an example I don't mind sharing. It actually displays upside down in the photos app. I'm sure it's the same issue.
Hum, I can not reproduce your issue with your image! :confused:
That is a very interesting bug :grin:
Can you screenshot the interface when it's misbehaving please?
Dang, that will sure make it harder to pin down. :( It really is weird.
Sure, happens on multiple clients, windows, linux, whatever, any browser Ive tried, firefox, edge, chromium.
Here is a screenshot

What the hell :p
If you upload the same image into a different name/folder, can you reproduce the same issue?
Just tried that when you said loading it to your nextcloud didn't have that result. Unfortunately that didn't work
But I just found the way a I shared it forced you to make a copy and that copy oriented correctly. Let me try sharing it this way.

Wow :grin:
SO even github is displaying it in reverse, but opening in a new tab works :)
I'm guessing your image is bisbehaving
haha wow!
Ok, well I can fix that myself then. Clearly It's not a photos bug. I'll just close this. Thank-you for your help

Must have been, Funny how it's been ignored up until now by a lot of other software
