+If you have @code{w3m} installed on your system, Gnus can display
+@acronum{HTML} articles in the article buffer.  The following
+variables are relevant:
+
+@table @code
+@item gnus-html-cache-directory
+@vindex gnus-html-cache-directory
+Gnus will download and cache images according to how
+@code{mm-w3m-safe-url-regexp} is set.  These images will be stored in
+this directory.
+
+@item gnus-html-cache-size
+@vindex gnus-html-cache-size
+When @code{gnus-html-cache-size} bytes have been used in that
+directory, the oldest files will be deleted.  The default is 500MB.

 Gnus will display some @acronym{MIME} objects automatically.  The way Gnus
 determines which parts to do this with is described in the Emacs
 @acronym{MIME} manual.
