title: Video thumbnail
body: <p>I am working on a site that people can submit the video's link.  Then I just embed it.  However, I want to get the thumbnail of the videos without saving the videos in my server.  So that when I list the vidoes, I can use the thumbnails instead of embedding all videos.</p>
  
  <p>My serve uses PHP.  Assume the video is in SWF format.</p>
  
  <p>is there anything in the  or  tag that I can 'grap' the thumbnail? or in PHP, is there anything that I can remotely get the thumbnail (or a frame ) of the remote video?  </p>
  
  <p>any idea?</p>
