title: adding image in pdf using Django pisa: standard {% static 'path/to/image' %} do not working
body: <p>I try to implement pdf output using pisa following this tutorial: <a href="https://www.codingforentrepreneurs.com/blog/html-template-to-pdf-in-django/" rel="nofollow noreferrer">https://www.codingforentrepreneurs.com/blog/html-template-to-pdf-in-django/</a></p>
  <p>and it works except for images that are not displayed</p>
  <p>I understand the problem deal with relative/absolute path between pisa and Django system but do not manage to resolve.
  I read the solution in the xhtml2pdf document using link_callback method but it dosen work and have no error</p>
  <p>If I pass the absolute url of images in context to my html template it works :</p>
  <pre><code>&lt;img class=&quot;logo&quot; src=&quot;{{ url }}&quot; alt=&quot;logo alima&quot;&gt;
  </code></pre>
