Most Fediverse software supports image uploads, so there’s no reason to use Imgur for image hosting. Hell, even on my small single-user server (atomicpoet.org), image hosting is easy peasy. Not only is Imgur not needed, they’re an annoyance for those of us who are used to seeing images natively on the Fediverse.
I know habits are hard to break, but just remember: this isn’t Reddit 🙂
Its been brought to my attention on a previous thread that if you’re attaching images to comments on Kbin, Lemmy users cannot see them.
I still very much dislike imgur though, so I wouldn’t suggest that as a solution. But embedding images into hyperlinks seems to be the best way to ensure your comment containing an image is viewed correctly by the wider fediverse.
