Content-Location ignored?

[jidanni@xxxxxxxxxxx]

I notice that even though images in multipart messages contain

  Content-Type: image/gif
  Content-Transfer-Encoding: base64
  Content-Location: http://www.ihaoke.com/html/blogpic/blog_pic_120601.gif

gnus and/or w3m attempt to get them from the network, instead of using
the images from within the message. See RFC 2616 part 14.14
Content-Location, perhaps.
Sample mail message: http://filebin.ca/ctvtmc/ihaoke-Content-Location-example.txt.bz2
My configuration: http://jidanni.org/comp/configuration/ .

The idea is that if <IMG src=> matches any Content-Locations in the same
message, it can then use those matching images, instead of needing to go
to the real location.

There I was reading offline, and unable to have the images appear where
they belong in the message.
