Do You Foresee Any Problems With This Approach To YouTube Videos?

I am trying to squeeze every excess byte out of my downloads. I noticed that even with the iFrame version of YouTube videos, users have to download almost 200K worth of data.

I decided to use the screenshot stored at YouTube (replace all occurrences of VIDEOID with a youtube video):



<div align=center id='vidVIDEOID' stlye='clear: both; margin:0; padding:0;'>

<img class='YouTubeScreen' rel='VIDEOID' src='' border='0' />


And use jQuery javascript like this:

$(".YouTubeScreen").click(function(e) {

var vid = $(this).attr('rel');

$("#vid" + vid).html('<iframe title="YouTube video player" width="640" height="390" src="' + vid + '?autoplay=1" frameborder="0" allowfullscreen></iframe>');
