display images inline in xterm (while using mutt)

[Globe Trotter via Mutt-users]

Hi,

If I use w3m -o ext_image_viewer=0 test.png, I can get the file test.png inside 
xterm.

I wanted to do the same on my mutt window (inside xterm). How do I do this?

I tried putting:

image/*;w3m -o ext_imageviewer=0 %s; copious output

However this does not work and gives me the options of w3m in the mutt window. 
How can I use this?

TIA!
