That would work just as well for blossom, but using the servers domain + sha256 as a URL allows it to be backwards compatible with any web browser or client that renders images from URLs

Makes sense. That is how I've already implemented the blossom integration in my app (just with a different 'kind' for server list - I'll switch it to standard)
Oh wait I've already used the right kind... has this bud been around longer? Somehow I've already implemented this exact flow in my app
