Yea, I can show external pictures, videos... heck I even put games on there from addictinggames.com
This code works fine for it, I got it from google.video, they have a put in your website link that gives you the code.
<embed allowScriptAccess="never" style="width:650px; height:400px;" id="VideoPlayback" align="middle" type="application/x-shockwave-flash" src="
http://farm.addictinggames.com/D78AQSAKQLQWI9/2159.swf" allowScriptAccess="never" quality="best" bgcolor="..ffffff" scale="noScale" wmode="window" salign="TL" FlashVars="playerMode=embedded"> </embed>
It's pretty much the same as a personal website except it doesn't allow anything other than html. Maybe this is why nobody does it... it can't be done :-?
