Problems with .JPG files, Nextcloud Hub 25.0.1

I’m not sure if this is a Nextcloud or PHP issue, but…

Any time I try to view a .jpg image file in one of my Nextcloud folders, I get the error shown on this screen snip..

Some initial web searching has pointed out this may be a lack of image support in PHP 8.1, but I’m not enough of a coder to chase it down.

Is this a known issue? Or something new?
