To expand on my MWE:

I have this patch on top of Nicolas's patch:

=====
diff --git a/lisp/ox-html.el b/lisp/ox-html.el
index 9e710e3e0a..410bb42eec 100644
--- a/lisp/ox-html.el

      ((and home use-abs-url)
       (setq raw-path (expand-file-name raw-path home))))

This adds the root and link instead of having the root be a subset of link
(hope that makes sense).

With that, here is the updated MEW:

=====
#+TITLE: ox-html root dir
#+OPTIONS: toc:nil
#+STARTUP: inlineimages
#+HTML_LINK_ROOT: /tmp/site/static/

An =image.png= exists at =/tmp/site/static/images/image.png=.

* TODO [1/2] This is how the image links should have worked with the link
root already specified
[[/images/image.png]]
- [X] The =HTML_LINK_ROOT= should to appended to the front of the above
link if
  that concatenated path is a valid one.
- [ ] Would also like =C-x C-o=, inline image display, etc. to work.
  - So a thought.. should the link root specification be made exporter
  agnostic?
