The manual explains in "Images in HTML export" that you can make an 
image a hyperlink like this:

[[file:highres.jpg][file:thumb.jpg]]

where thumb.jpg becomes the <img> 'src' and highres.jpg becomes the <a> 
'href'. One might infer it should also be possible to link to something 
other than an image, like this:

[[http://gnu.org][http://example.com/gnu-head.jpg]]

For example, try exporting this file:

#+begin_src org
Some initial text.

[[http://example.com/a.png]]

Some text between images 1 and 2.

[[http://eeyup.com][http://example.com/b.png]]

Some text between images 2 and 3.

http://example.com/c.png

Some trailing text.
#+end_src

You do indeed get

<a href="http://eeyup.com"><img  src="http://example.com/b.png" 
alt="b.png" /></a>

in the output, but the exporter doesn't regard the image as standalone, 
so it doesn't get put in a <div> (or, in HTML5 mode, <figure>) like the 
others, and if you add a #+CAPTION, no caption will be included.

The attached patch to master shows how this can be fixed, but I hesitate 
to recommend applying it because two new bugs are immediately apparent:

1. Figure numbers are screwed up. If you add #+CAPTIONs to each image in 
the above file, the figure numbers go Figure 1, Figure 3, Figure 4.

2. The <a ...> ... </a> gets wrapped around the whole <div> or <figure>, 
not just the <img>. This breaks markup validity (<div> isn't allowed in 
<a>) and makes the caption, if you have one, into a giant hyperlink.

I think I'm going to stop working on this issue for now, but at least 
what I've done could be helpful for anybody else who wants to go further 
down the rabbit hole.

P.S. I sent a request for a copyright-assignment form earlier today.

I can't follow this rabbit right now, but I hope someone can
tidy things up a bit here (been there, done that...)

Indeed. Would you mind testing the following patch against master? It
should fix the issues.

Subject: [PATCH] ox-html: Fix standalone hyperlinked images

* lisp/ox-html.el (org-html-inline-images): Change default value and
  remove `maybe'.
(org-html-format-inline-image): Remove functions.
(org-html--wrap-image, org-html--format-image,
org-html-inline-image-p): New functions.
(org-html-latex-environment, org-html-latex-fragment): Use new
functions.
(org-html-standalone-image-p): Use new functions.  Also remove an
unused optional argument.
(org-html-link, org-html-paragraph): Correctly export hyperlinked
images.

This patch permits the back-end to recognize links like:

  [[http://orgmode.org][http://orgmode.org/img/org-mode-unicorn-logo.png]]

as standalone, so they can get wrapped within a proper environment and
get captions.

Thanks to Kodi Arfer for reporting it.
