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.
Yep it is super annoying atm. Getting to where Reddit + RES was for any Fediverse frontend would be my ideal, but I know that is likely a bit away yet.
However currently Imgur links require me do multiple click/page loads to see anything with Kbin and right now that sucks because there are a fair amount of posts that link to them. And saying, well people should just use X/Y/Z to host it instead is a bad solution. The solution should always be to make X/Y/Z a better/easier hosting option while still supporting other hosts.
