Here is the current HTML code available. There might be multiple DIV with the class "ow_video_list_item ow_small".
<div class="ow_video_list_item ow_small">
   <a href="http://www.site1.com">
      <img src="http://img.youtube.com/vi/xVrJ8DxECbg/default.jpg">
   </a>
   <div class="ow_video_item_title">
      Site 1
   </div>
</div>
I want this HTML to be modified as found below.
<div class="ow_video_list_item ow_small">
   <img rel="xVrJ8DxECbg" src="http://img.youtube.com/vi/xVrJ8DxECbg/default.jpg">
   <div class="ow_video_item_title">
      <a href="http://www.site1.com">Site 1</a>
   </div>
</div>
PS: The format of the IMG src attribute will not change. The value "xVrJ8DxECbg" is the video ID of the video in Youtube.
