images previews showing in the wrong orientation

[pB4Di486Ejh59TcGJci5K6ZF7]

In multiple sections of the UI I've noticed some images previews are showing as horizontal however when selected the image corrects to the vertical orientation. I've noticed this in the Slideshow and on a users album page of a user

Here is example from the Slideshow section. First image is the preview and the second is showing once selected

The next image is showing from the album view of that user

This was fixed in #4592.

However, the updated library requires a newer version of PHP.

So the fix cannot be released until we release webtrees 2.2
