No, since the inline request is done seperately, you just need to use a
different Accept header for that request.  You don't need any new
headers.

This can be done at the moment: our server has been doing this for over
a year now, and it works for everything (except WinMosaic, which is a
bit broken in this respect).  No new magic is needed, you just have to
use a server which supports multiple types and configure it up properly.
 This is the whole purpose of the Accept headers (well, there may be
other reasons, but who cares :), and it allows you to even convert the
images into the correct format on the fly (we had this enabled in our
server for a while, and it kept converting gif's into ascii art on
terminal interfaces. Yuck :)
