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 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 buffer, which is a good signal~

Please let me know if there's any further instruction. And thanks for the help~~

Best,

Chao

Alright, we're getting somewhere now.

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

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

If this one doesn't work as well, I can proceed from there.

regards,
