Lemmy Support

I'm not against including an ipfs layer in pict-rs, but the complexity would go way up. Federating an image between lemmy servers would require sending the ipfs uri between servers via activitypub, and then each receiving server sending that uri to pict-rs. pict-rs would then need to decide, on each server, if the ipfs-stored image matches that servers' image requirements (max filesize, max dimensions, etc), and if it does, then that pict-rs server would request to pin the image. I don't know exactly how ipfs pinning works, but ideally it would only be stored locally if it isn't already stored in at least N other locations. If the remote image doesn't match the local server's configuration, it could either be rejected or downloaded & processed (resized etc).

Serving ipfs-stored images that aren't replicated locally might also be slow, but I won't know for sure unless I actually try building this out.
