title: Showing different images in Highmaps when moving the mouse cursor to a point
body: <p>I'm trying to implement the next feature in Highmaps: when a user moves the mouse cursor to a specific point an image is displayed along with text data, you know, on any Highcharts chart, stock or map detailed information about point is appeared in a small window when a user moves the cursor on that point. </p>
  
  <p>Problem is that I don't know how to insert images in these small containers - I think this post <a href="https://stackoverflow.com/questions/34983462/showing-image-with-variable-src-in-tooltip-of-highcharts-scatter-plot">Showing image with variable src in tooltip of Highcharts scatter plot</a> is somehow related to my problem, but there (and in the majority of questions concerning embedding images in Highcharts) users usually try to insert images statically into a legend or a tooltip and thus their tips are not helpful in my case.</p>
  
  <p>Hope someone can help me.</p>
