code: @Override
      protected Element getImage(final Element rssRoot) {
  
          final Element eChannel = rssRoot.getChild("channel", getRSSNamespace());
  
          if (eChannel != null) {
              return eChannel.getChild("image", getRSSNamespace());
          } else {
              return null;
          }
  
      }
docs: It looks for the 'image' elements under the 'channel' elemment.
