Posts on mobile don't orient correctly sometimes.

Most of the photos taken from phone display like that on all platforms. Discord is among these apps where I experienced this problem, too. I don't know why. Maybe it's a bug or a feature of built-in PHP image library.

I'll look into some articles on this issue. 😎

Can you give me some more info on what functions you are using to process and load the images so I can look this up better?

I found the potential reason of why is it happening: some phones don't rotate photos taken from an angle different from the default one, but rather save it as regular photos and store the angle in EXIF data. Mobile software handles such metadata and rotates these photos back juts fine, but PHP-GD either ignores this value or resets it to zero. Tried to explain it as easy as possible. There's a potential solution for this I found and going to try in this update.

Also, there's no such a bug as "while I post in your post" mentioned on the screenshot, or at least I've never stumbled upon it and don't know how to reproduce it.

I'm not sure why I wrote "while I post in your post" that's a weird line.
