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 🙂
I will add that many of us who work remotely using publicly accessible wifi also use VPNs, and Imgur actively blocks IPs from multiple commercial VPN providers. If you want those users to see the image you’re sharing, Imgur is not the way to go.
Pixelfed works well with other Fediverse services like Kbin and Lemmy. Try hosting there!
