title: Display pdf image in markdown
body: <p>Is this possible? Everything I'm google leads me to converting markdown to PDF. But I want to display a PDF image in a markdown file. This is my example:</p>
  
  <pre><code>![hustlin_erd](erd.pdf)
  </code></pre>
  
  <p>If i use a regular image, it works just fine. Also I'm aware of converting PDF to image.</p>
