@Marek Bachmann @Friendica Entwickler Marek is it from an iPhone, I can remember that iPhones often have the wrong orientation of the photo, I had this a lot with photos my sister send me by Signal. She has an iPhone.
They are portraits for me when I click them. Desktop + Browser. My instance uses the Frio theme + some custom CSS on top that should not affect how these photos are displayed. idk if that's the sort of input you were looking for.
@Hypolite Petovan a general question which surely is in the scope of your expertise: Is there some method in git to check when a specific method / code block was last changed by a commit? In this specific case, I would like to check when and what was changed in the Images::getScalingDimensions($width, $height, 90); method to confirm / rule out being the cause of this bug.
