The most performant implementation would be to generate the URL for the
image using a fixed suffix (relative to the result object).  E.g., ::

  <ul>
    <li tal:repeat="event context/listEvents">
      <a href="event/getUrl">
       <img src="string:{event/getUrl}/event_image" />
       <span tal:content="event/title">TITLE</span>
      </a>
    </li>
  </ul>

You could achieve that fixed suffix either by mandating a fixed object
ID for the image, or by adding a method / view to the event which
redirected to the actual image URL.
