Priority: Remove third-party image server dependency
Currently, blurt.blog and blurt.world reply on images.blurt.buzz, this domain belongs to a third-party that is no longer active on Blurt.
Luckily the underlying infrastructure is the foundation's own image server which I believe images.blurt.buzz points to. We need to use our own subdomain for this, we have three, I am not sure which one is the correct one out if images.blurt.blog; img.blurt.world or imgp.blurt.world as can be seen on Cloudflare.
