title: MRSS - Display poster/background image on audio-only feed
body: <p>Not sure if this is possible, but I need to display a poster/background image in an MRSS feed where I am playing audio only, not sure if this can be done. As at the moment, when the player accesses this feed, it plays the audio, but with a black background. I am hoping to add an image there, but not sure what element to use. I have checked the MRSS specs here <a href="http://www.rssboard.org/media-rss" rel="nofollow noreferrer">http://www.rssboard.org/media-rss</a>, but it doesn't look like they've been updated for a while and I cannot find how to add such a background image.</p>
  
  <pre><code>&lt;item&gt;
           &lt;title&gt;My Title&lt;/title&gt;
           &lt;link&gt;&lt;/link&gt;
           &lt;description&gt;My Description&lt;/description&gt;
           &lt;guid isPermaLink="false"&gt;&lt;/guid&gt;
           &lt;media:category&gt;All&lt;/media:category&gt;
           &lt;media:category&gt;Music&lt;/media:category&gt;
           &lt;media:content url="http://linktoaudiofile.mp3 language="en-us" medium="audio" isDefault="true"&gt;
              &lt;media:title type="plain"&gt;Title&lt;/media:title&gt;
              &lt;media:description type="html"&gt;Description&lt;/media:description&gt;
              &lt;media:thumbnail url="icon_large.png" /&gt;
              &lt;media:credit role="author" scheme="urn:ebu"&gt;Author&lt;/media:credit&gt;
              &lt;media:copyright url="coprightURL" /&gt;
           &lt;/media:content&gt;
        &lt;/item&gt;
  </code></pre>
  
  <p>Any ideas? Thank you.</p>
  
  <p>Happy to also understand if this can be done a different way, such as using a player with the  element instead?</p>
