That's exactly what I am talking about.

I came up with a solution to my need. I am posting here in case someone
else needs it. I don't like it because it involves Python and the
function is hard coded with the nnml backend.

(defun ivan-gnus-save-attachment ()
  "Save all atachments include cid inline attachments."
    (interactive)
  (let ((output-buffer (get-buffer-create "output"))
        (file-name (nnml-article-to-file (gnus-summary-article-number))))
    (switch-to-buffer output-buffer)
    (erase-buffer)
    (insert "The following files were extracted:\n\n")
    (call-process
     "extract-inline-attachment.py" nil output-buffer t file-name)))

I have attached the python script. I would rather do it all in elisp but
whenever I look at gnus code my brain melts ;)

I didn't know that command. Nice! However it gets too long with multiple
images.

C-d C-n C-n C-n C-n <return> K b C-o C-n o ~/tmp/foo.png RET

And I have to do the K b sequence for each image...

That would be nice.

Why?

Thank you for correcting my Japanese!
