title: Image Load Events
shortdesc: Example using image load events.
docs: >
  <p>Image sources fire events related to image loading.  You can
  listen for <code>imageloadstart</code>, <code>imageloadend</code>,
  and <code>imageloaderror</code> type events to monitor image loading
  progress.  This example registers listeners for these events and
  renders an image loading progress bar at the bottom of the map.</p>
