Pictures have size. As a rule of thumb, every part of picture is as important as every other. Otherwise, why would it be there? That’s why cropping pictures leads nowhere. I mean, yes, your page looks tidy and organized now, but what’s the point if I can’t see content? And I came for the content, not for the clean and tidy page, damn it! Besides, it’s not like there’s lack of vertical space in infinite vertical timeline, you know?
P.S. It’s double terrible because crop means you have to click on a picture, and clicking on a picture makes you lose everything! See grumpy.website/post/0TRVXIFch
