Accept header and inline images

Most Web browsers send Accept: */*  (perhaps after a short list) on the 
basis that they are prepared to download anything using a dialog box.
Thus, Accept is not very useful, unless to choose between alternates 
using a "q" factor.

How about an Inline-Accept header, which would list only those MIME types
supported for inline rendering? 

A browser with images turned off would send an empty header, and a
negotiating server might deliver a different, text-only, page. The same
header might include entries for background sound and embedded applications
(though it is possible to write JavaScript code to negotiate this kind of
thing).
