Sorry about the image issues. We know about the issue, and Kaity will be looking at it today. Our matrix instance came under a pretty serious attack by transphobes this last week, and keeping it safe has been our big focus, so this has sort of lingered.
Catbox.moe works pretty well, is free, not being monetized, and otherwise just really handy!
I am almost universally unable to reach catbox.moe or view any images from them.
Really? I can view posts with catbox images and have a recent post with a catbox image that other people could see :/ I remember reading some countries dislike catbox.moe so perhaps your DNS blocks them? Could you try temporarily switching to another DNS to see what happens?
