Picon Basics Picons Easy Picons
To have Gnus display Picons for you, you must be running XEmacs 19.13 or greater since all other versions of Emacs aren't yet able to display images.
Additionally, you must have
x support compiled into XEmacs. To
display color picons which are much nicer than the black & white one,
you also need one of
gif compiled into XEmacs.
If you want to display faces from
X-Face headers, you should have
xface support compiled into XEmacs. Otherwise you must have
netpbm utilities installed, or munge the
gnus-picons-convert-x-face variable to use something else.
