@section Viewing images
When you run Emacs in GUI-mode, images attached to the HTML message will
be shown inline in the message view buffer. To disable this, set
@code{mu4e-view-inhibit-images} to @t{t}. By default, external images
in HTML are not retrieved because they may be used to track whether
you've read the message or not and so lower your privacy. You can
specify what URLs to block by setting @code{mu4e-view-blocked-images} to
a regex or to a function that will receive the message as an argument.
For example, to enable images in Github notifications, do the following:
@lisp
(defun my/mu4e-view-blocked-images (msg)
(if (mu4e-message-contact-field-matches
msg :from "notifications@@github.com")
nil "."))
(setq mu4e-view-blocked-images #'my/mu4e-view-blocked-images)
