@xavcactus,
Adding an image to the chart is not available as an inbuilt-feature as of now, but we do have it in our wish list. The tutorial in our documentation shows how to position an image over the chart by adding a few lines of extra code. As images are positioned on top of the chart externally, it doesn’t get exported. However, with the help of third-party libraries like html2canvas you can export chart & image together as shown in this JSFiddle.
