Hosting the images directly on the lemmy/kbin instance creates imo unnecessary traffic to the servers. I don't know if admins can disable selfhosting images, but considering the low-powered machines almost every instance is currently hosted on, I would assume it would be in everyones self-interest to outsource image hosting (at least for now).
It's kinda obvious, isn't it. Just recreate the community/magazine on lemmy/kbin :D
Maybe advertise your community in the subreddit while telling everyone that you have been replaced as a moderator.
