I want to create clickable image links in org-mode. This would be equivalent to:

<a href="path-to-file">
   <img src="path-to-image">
</a>

Currently, I can display inline image previews just fine, with [[path-to-image]] followed by org-toggle-inline-images. What I would like to do now, is add support for [[path-to-file][path-to-image]].

Any ideas?
