Quick and dirty: you could just set the embed code as a global variable somewhere:
<script type="text/javascript">
var embedCode = '<object data="http://blip.tv/play/gYMo_vAmAA" type="application/x-shockwave-flash" height="500" width="600"><param name="src" value="http://blip.tv/play/gYMo_vAmAA"><param name="allowfullscreen" value="true"></object>'
</script>
Then put the image in a container div and replace the container's innerHTML onclick:
<div id="videocontainer">
<img src="yourimage.jpg" onclick="document.getElementById('videocontainer').innerHTML = embedCode;" height="500" width="600" />
</div>
