Unrelated but imgur is basically malware at this point. I had to click through so many layers of nagging popups (including a “don’t support us” button, then a severely low-contrast “view in safari” button on a dialog explicitly designed to get me to accidentally click the app link), then when I finally got to your picture, any sort of interaction with the page whatsoever, including pinch-zooming to see the image, just took me away to a different page altogether.

I sincerely hate imgur and hope the whole site goes bankrupt, and I can’t stand it when anyone links to them.

I'm glad that at times like these, I switched to Brave browser on all of my platforms (desktop and mobile). I can't recommend it enough.

Can you suggest a low-effort alternative I can use in future?

Yeah can't see that lasting. I wish someone would make one with limited adverts that just pays for the hosting and moderation costs. How hard can it be?

Here's a comparison of alternatives

Also it's not accessible in the UK without workarounds that I'm not going to bother with for that dumpster fire of a site.

Yeah, imgur had very simple & humble origins and fostered a surprisingly active, reddit-like community (though I'm sure imgurians would resent that particular comparison), and then holy shit it just turned into a bizarrely bloated overstuffed hodgepodge of fire-garbage. I just looked at the homepage for the first time in forever and—wait, what? "Arcade"?

Bleh.

strange, I got no pop ups at all
