UBBCentral does not have the PHP exif_read_data function installed/enabled (uncommon).
https://www.php.net/manual/en/function.exif-read-data.php

This is a demo of what happens in that case.


UBB.threads 7.7.3 and newer, with jpeg image orientation fixes

IMAGE 1 ORIENTATION with GD2, function_exists('exif_read_data') = false
Firefox: Wrong
Chrome: Wrong
Safari: Wrong
Edge: Wrong

vs

IMAGE 2 ORIENTATION with ImageMagick, function_exists('exif_read_data') = false
Firefox: Good
Chrome: Good
Safari: Good
Edge: Good
