title: Render SVG images on each point of gantt chart in highcharts
body: <p>I want to put some images as SVG on each point in Gantt chart, I've tried something like below:</p>
  <pre><code>function (chartt) { // on complete
              chartt.renderer.image('imageURL.png',100,100,30,30)
                  .add();
  }
  </code></pre>
  <p>But after running this code, the image will be shown on the corner of the page. I want to draw images on each point in the chart and set their position related to its point.</p>
