idk for sure but I'd guess it's if an image is taller than your screen you can either force it to fit or allow it to go beyond the screen; like you'll have to scroll to get to the bottom of the image
I believe this is correct. So an infographic for example would need to be scrolled before you get to the comments. If it doesn’t ignore screen height the preview will compress it making it look more narrow, working as more of a preview
Say, for example, somebody (not naming names) posts an image of beans whose aspect ratio is 10x taller than that of your screen's... This setting makes it so that you have to scroll forever to get past it because it won't resize its height to fit your screen's height.
It will actually still conform a bit better than that, trying to stay at 90% of screen height. Otherwise you could have some super annoying images pop up. With the setting turned off images are scaled to 65% of screen height.
But yea, this is correct.
Ah okay, I see that I made an assumption of how memmy would behave based on the issue wefwef had to address the other day. I feel like this setting could possibly be worded a little better then because it certainly sounds as though all images would be their full height (and zoomed to fit the width of the user's screen) with it enabled.
Thanks for the replies! This is what I’ve assumed it did but I guess I haven’t found a post yet to properly see the functionality.
