Hi Oleh,

Thanks a lot for the detailed instruction again, and the screencast is a
good job as well! I just did the testing. Please see below.

1. Have you made any customizations to `org-download`? It's easier for
me to proceed with the defaults.

*-- No, all I did is (require 'org-download)*

2. As I'm testing now, I can get a "Wrong type argument:
   number-or-marker-p, nil" error if the org-mode file in question is
   empty or the cursor is before the first heading. Is this the case for
you?
   I'll fix this case soon anyway.
-- *Not really, I made a test.org <http://test.org> then insert some
heading, then tried (org-download-yank) with the web address on top of
kill-ring, which did not trig the download events as well.*

3. If this doesn't work, try the following simplified function:

    (defun org-download-yank-1 ()
      (interactive)
      (let ((filename "./foo.png"))
        (org-download--image
         "https://www.google.nl/images/srpr/logo11w.png"
         filename)
        (insert (format "[[%s]]" filename))
        (org-display-inline-images)))



*-- This one works! The google logo gets into my test.org <http://test.org>
buffer, which is a good signal~*
Please let me know if there's any further instruction. And thanks for the
help~~

Best,

Chao
