Thanks! The image: format attribute is not defined in the User Guide (section 29.5), AFAICT, but I was hoping one existed.

Regarding render.githubusercontent.com site, I think it was more or less an accidental discovery by someone that this functionality exists for other purposes - https://gist.github.com/a-rodin/fef3f543412d6e1ec5b6cf55bf197d7b . It seems to be undocumented and probably not a robust site to rely on (they might easily decide to block access from outside their intended userbase, for example), though it is useful.
