HTML coverter creates wrong relative image url

[kreutzr]

Hi

I am using asciidoctorj-pdf V2.3.19 to render a manual from ADOC to PDF and HTML.
The manual starts as follows:

= ResponseDiff - Version 0.13.1-SNAPSHOT
:encoding: utf-8
:lang: de
:toc: left
:toclevels: 5

image::img/responsediff-logo_320x160.png[ResponseDiff]

== What is ResponseDiff?
...

While the resulting PDF shows the logo as intended, the HTML result holds a broken link "**doc/img/**img/responsediff-logo_320x160.png" instead of "img/responsediff-logo_320x160.png".
Here is the relevant HTML section.

...
<div id="content">
<div id="preamble">
<div class="sectionbody">
<div class="imageblock">
<div class="content">
<img src="doc/img/img/responsediff-logo_320x160.png" alt="ResponseDiff">
</div>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_what_is_responsediff">What is ResponseDiff?</h2>
<div class="sectionbody">
...

Thanks :)

Btw: I wanted to emphazise the "doc/img/" part. The double '*' are not part of the url.
