title: replace image with a video embeded
body: <p>Hi I'm trying to modify a web page so that it loads faster.
  Since I have some videos embeded (blip.tv but can change it to youtube if it helps) I was wondering if you could load an image where the video should be and on click replace the image with the video and start playing (without reloading the whole page). 
  I think I've seen this before, but can't find it anywhere anymore!
  right now the code to embed I use is:</p>
  
  <pre><code>&lt;object data="http://blip.tv/play/gYMo_vAmAA" type="application/x-shockwave-flash" height="500" width="600"&gt;&lt;param name="src" value="http://blip.tv/play/gYMo_vAmAA"&gt;&lt;param name="allowfullscreen" value="true"&gt;&lt;/object&gt;
  </code></pre>
  
  <p>Thanks</p>
