I want to insert a link like :

[[http://foo.org/bar][file:foo.jpg]]

and export it to html. I assume that it should result in a clickable image.
Unfortunately, some assertion fails by doing this.
If I remove the assertion :

diff --git a/contrib/lisp/org-e-html.el b/contrib/lisp/org-e-html.el

                (funcall org-e-html-standalone-image-predicate paragraph))

I get a result but I'm afraid there are a couple of spurious <p></p> tags.
