called with a @acronym{MIME} handle as the argument.

@vindex mm-inline-text-html-with-images
-Some @acronym{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 information from
-leaking by setting this option to @code{nil} (which is the default).
-For emacs-w3m, you may use the command @kbd{t} on the image anchor to
-show an image even if it is @code{nil}.@footnote{The command @kbd{T}
-will load all images. If you have set the option
-@code{w3m-key-binding} to @code{info}, use @kbd{i} or @kbd{I}
-instead.}
+If this is non-@code{nil}, inhibit displaying of images inline in the
+article body. It is effective to images that are in articles as
+@acronym{MIME} parts, and images in @acronym{HTML} articles rendered
+when @code{mm-text-html-renderer} (@pxref{Display Customization}) is
+@code{shr} or @code{w3m}. In Gnus, this is overridden by the value
+of @code{gnus-inhibit-images} (@pxref{Misc Article, ,Misc Article, gnus,
+Gnus manual}).
+
+@item mm-html-blocked-images
+@vindex mm-html-blocked-images
+External images that have @acronym{URL}s that match this regexp won't
+be fetched and displayed. For instance, do block all @acronym{URL}s
+that have the string ``ads'' in them, do the following:
+
+@lisp
+(setq mm-html-blocked-images "ads")
+@end lisp
+
+It is effective when @code{mm-text-html-renderer} (@pxref{Display
+Customization}) is @code{shr}. In Gnus, this is overridden by the value
+of @code{gnus-blocked-images} or the return value of the function that
+@code{gnus-blocked-images} is set to (@pxref{HTML, ,HTML, gnus, Gnus
+manual}).
