title: How to display an image in a QWeb report?
body: <p>I extended the 'report.external_layout_footer' qweb view to display image.</p>
  
  <p>Below is my code in the file reports/external_layout.xml:</p>
  
  <pre class="lang-xml prettyprint-override"><code>    &lt;template id="report_footer_custom" inherit_id="report.external_layout_footer"&gt;
          &lt;xpath expr="//div[@class='footer']" position="replace"&gt;
              &lt;div class="footer"&gt;
                      &lt;img t-att-src="'data:image/jpeg;base64,/var/www/cbl_openerp/openerp/cap_addons/cap_sale/img/footer.jpeg'"/&gt;
                      &lt;ul class="list-inline"&gt;
                          &lt;li&gt;Page:&lt;/li&gt;
                          &lt;li&gt;
                              &lt;span class="page"/&gt;
                          &lt;/li&gt;
                          &lt;li&gt;/&lt;/li&gt;
                          &lt;li&gt;
                              &lt;span class="topage"/&gt;
                          &lt;/li&gt;
                      &lt;/ul&gt;
                  &lt;/div&gt;
          &lt;/xpath&gt;
      &lt;/template&gt;
  </code></pre>
  
  <p>And here is my <strong>openerp</strong>.py content :</p>
  
  <pre class="lang-python prettyprint-override"><code>...
  "depends": ["base","sale","report"],
  ...
  "data": ['sale.xml',
          'reports/reports.xml',
          'reports/external_layout.xml',
          'reports/informations_prestation.xml',
          'views/product_template.xml',
          'filter.xml'],
  ...
  "images":['img/footer.jpeg',],
  ...
  </code></pre>
  
  <p>But when I print a sale order, i can't view my image at the bottom of the page.</p>
  
  <p>Does anyone have any suggestions?</p>
