In the article buffer the following lines appear:

----------------------------------------------------------------
it is not supported.  Does your Gnus display the following image
in the article buffer?

[2. image/png; emacs.png]
----------------------------------------------------------------

. When I left click on the last line, a new windows opens up
where the image *is* displayed, although not properly in the article buffer.

These are the results:

(image-type-available-p 'gif)
nil

(image-type-available-p 'jpeg)
nil

(image-type-available-p 'tiff)
nil

(image-type-available-p 'xbm)
t

(image-type-available-p 'xpm)
t

(image-type-available-p 'png)
nil

As I wrote in one of my previous messages, I have Emacs CVS 21.3.50
installed one month ago, which includes gnus 5.11.
In fact, when I do `M-x gnus-version', the echo area shows:

Gnus v5.11

Yes, it was my mistake. Now in my .emacs there is:

(require 'w3m-load)

, and in my .gnus.el:

(setq mm-text-html-renderer 'w3m)
(setq mm-inline-text-html-with-images t)
(setq mm-w3m-safe-url-regexp nil)

. Thanks again for your precious help,
cheers,
