title: Insert image into documentation generated by libdoc
body: <p>I am currently writing a custom <code>Python</code> library for <code>Robot Framework</code>. I use  <a href="https://robot-framework.readthedocs.io/en/2.9.2/_modules/robot/libdoc.html" rel="nofollow noreferrer">libdoc</a> to generate documentation for it from <code>docstring</code>.</p>
  
  <p>The command which I use to generate the documentation: <code>python -m robot.libdoc resources/pageobjects documentation.html</code>. Now I also want to include some screenshots in it but I didn't find any possible solution for that. If I know correctly, the docstring can be written in <code>reStructuredText</code> and with the use of it images could be inserted like this: </p>
  
  <pre><code>.. image:: my_screenshot.png
  :height: 100px
  :width: 200 px
  :scale: 50 %
  :alt: alternate text
  :align: right
  </code></pre>
  
  <p>With this the raw text will be displayed in the documentation file. How can I achieve to include the images?</p>
