Displaying Images in HTML Mail

Displaying Images in HTML Mail

[Les Harris]

Can anyone point me in the right direction for configuring Gnus to
display images in HTML mail?

Running Gnus v5.13 as shipped with Emacs 24.4.  EWW renders the HTML in
the Message buffer fine but loads no images. If I go to a URL outside of
Gnus using EWW it renders images fine.  I have set gnus-inhibit-images
to nil in my Gnus config and yet I still have no images showing in the
Gnus message buffer for an HTML mail.

I have yet to find the relevant configuration for this so I thought I
would ask and see if anyone knew.

Any help appreciated, thank you.

On which OS is this?  On what platform is Emacs runnings,as the
Windows port has a few steps that you need to follow.

The following thread might be useful

If you're able to see png/jpeg outside of gnus, then the above
instructions are moot.

Thanks for the response Sivaram.  Sadly, I am running GNU/Linux (and EWW
displays images fine outside of GNUS).

So the search continues. I'll keep looking.  I imagine most people using
GNUS don't care about images in HTML mail but for a few select senders I like
seeing it (namely some hobby related bacn mails).

Before you asked i did not know, but i know how to find out:

 M-x apropos RET gnus-.*image RET

If you do this and post your findings, then together we will
have answered this question in the most fulfilling way, IMHO.

Thank you for your patient reply.  gnus-article-show-images does in fact
display the images in HTML mail once invoked.

Am I correct in thinking I should add this to gnus-article-mode-hook if
I want it invoked automatically?

That depends on whether or not it works for you, i suppose.  :-D
Take courage, backup $HOME/* somewhere safe, and try it out!  If
the result is as you desire, cool, write it up for the archives;
if not, cool, public discourse goes on -- no worries either way.

Hm. So gnus-article-show-images works when invoked manually. I've tried
adding it to gnus-article-mode-hook by adding/executing the following:

(add-hook
    'gnus-article-mode-hook
    (lambda ()
            (gnus-article-show-images)
            (message "Potentially show images...")))

However when opening an HTML mail with images this seems to have no
affect (manually invoking the command of course works). I can see the
'Potentially show images...' text in the *Messages* buffer so I know the
hook is executing.  Maybe the article mode hook is executing too early?
Or perhaps gnus-article-mode-hook is the incorrect hook to place the funcall.

Yes, that might be the reason.  Try `gnus-article-prepare-hook' instead.

Yes, this did the trick.  Thank you both for your help. The final
configuration is as follows:

(add-hook
    'gnus-article-prepare-hook
    (lambda ()
            (gnus-article-show-images)))

I've added some filtering in there so only a certain class of emails
will execute the show images function but that is the core.

You could also look at the following variables:
mm-inline-text-html-with-images, mm-w3m-safe-url-regexp
