Too tiny; didn't (couldn't) read. Although I seriously doubt that was "sage"... :p
If you follow the link, Reddit's shit UI makes it impossible to zoom like a proper picture. Please don't link to Reddshit: it's terrible to read because they fuck with image URLs, and it also gives them traffic. Any rehosting would be better and I think Lemmy even has first party support for it.
If you're on a phone, I expect pinch zoom works. I'm on desktop which is perfectly fine until a website goes out of its way to make it not fine. Reddit, being obviously scummy, does, though.
