Thanks. I installed the packages zlib-1.2.2.tar.gz and
libpng-1.2.8-config.tar.gz and then reinstalled Emacs CVS 21.3.50,
and now I *can* see in the article buffer the image you sent me in your
message.
However, there are other html images I still can't view with gnus.
Shall I install also the libraries for gif, jpeg and tiff?
I'm sending to your private address: yamaoka@jpl.org
an html image I still can't view with gnus.

Thanks indeed,
Rodolfo
