Could we not create a new URI syntax similar to the way multipart/related
emails work? So that either the image is attached to the message or
indicates where the client can download it from using IBB or from public

e.g. multipart/related emails attach all the images inline and in the HTML
put something like.

<img src="cid:123456789">

where the cid refers to the image cid attached to the email.
