title: pdfkit not converting image to pdf
body: <p>I am using PDFkit with python to convert an html page to pdf. In the html there is only one image tag in body with src pointing to a complete url like:</p>
  
  <pre><code>&lt;html&gt;
      &lt;body style="margin: 0px;"&gt;
          &lt;img style="-webkit-user-select: none; cursor: -webkit-zoom-in;" src="https://blah.blah.com" height="768"&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>However When I convert html to pdf like this:</p>
  
  <pre><code>pdfkit.from_file(file, 'labels.pdf', configuration=config)
  </code></pre>
  
  <p>I get a blank page with a box with border instead of image.</p>
  
  <p>Why is pdfkit not converting image?</p>
  
  <p>I read somewhere that we have to give full image path including domain name. But the image url I am providing is complete. Then what I am doing wrong?</p>
