+This function will be used to convert the HTML to the text. There are
+two pre-defined functions: @code{mm-inline-text-html-render-with-w3},
+which uses Emacs/w3; and @code{mm-inline-text-html-render-with-w3m},
+which uses emacs-w3m (see @uref{http://emacs-w3m.namazu.org/} for more
+information about emacs-w3m). The function will be called with a MIME
+handle as the argument.
+
+@item mm-inline-text-html-with-images
+Some HTML mails might have the trick of spammers using @samp{<img>} tags.
+It is likely to be intended to verify whether you have read the mail.
+You can prevent your personal informations from leaking by setting this
+option to @code{nil} (which is the default). It is currently ignored by
+Emacs/w3. For emacs-w3m, you may use the command @kbd{t} on the image
+anchor to show an image even if it is @code{nil}.

Some @sc{mime} agents create parts that have a content-disposition of

overridden if we are able to, and want to, display the part inline.)
However, users may prefer other types instead, and this list says what
types are most unwanted. If, for instance, @samp{text/html} parts are
very unwanted, and @samp{text/richtech} parts are somewhat unwanted,
