So, SSO allows overriding avatars, but if I’m not mistaken it just downloads the avatar image and stores them in the Discourse system.
Is it possible to actually allow overriding the URL, maybe providing a set of multiple prescaled images? I’m storing them on S3 with a Varnish cache in front, so it reduces my caching effectiveness and more or less doubles the costs to have two sets of avatars.
To do this would require a redirect for each avatar, which seems rather messy. It’d be nice if I could use external_id in there, then I could generate the actual URLs
