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 🙂
Image hosting is always easy, it’s never cheap. That’s the difference between an instance with tens of thousands of users and your server with 1.
Yeah even for large Media uploads I’ll probably not use my own instances server and instead use something like YouTube or streamable. Since many instances don’t even support displaying large Media at all i noticed. Like i uploaded a multiple hundreds MB video on my instance and on all Mastodon based instances it showed the file not being available.
