So that is an imgur link not an attachment.
We used to automatically download them and host them. I need to fix that script on the new server and I am not doing that until Monday or Tuesday probably. Maybe sooner but don't hold your breath.
The good news is that there is nothing wrong with actual image attachments, it's all about the script automation. Since we are on cloudflare now I think they block us from hotlinking directly. It should all be fixed once I script a cleanup of all the links.
Long story short, don't worry, just wait a few days.
