How to integrate an image (set via local path) in the exported HTML in emacs?

I would like to export an HTML file that contains some images (added via local path) to appear outside my computer. How can I integrate/embed/burn the image in the file for public view?

I can successfully manage to do this on R Markdown but unable to pull it off on emacs as I have only started using it.

Here's what I typed:

#+CAPTION: I-V curve for a diode
#+NAME:   fig:diode_1
#+attr_html: :width 250px
[[C:\Users\Documents\thres.png]]

I am hoping to get the local image exported into the final HTML document permanently.

Solution

Copy this code into the *scratch* buffer and C-M-x it. Then export the .org file to html as usual.

(defun org-html--format-image (source attributes info)
  (format "<img src=\"data:image/%s;base64,%s\"%s />"
      (or (file-name-extension source) "")
      (base64-encode-string
       (with-temp-buffer
     (insert-file-contents-literally source)
     (buffer-string)))
      (file-name-nondirectory source)))

It puts the images directly into the html file thanks to base64 encoding.
