I want to be able to paste YouTube video and link of pics from other site.

Actually i would like to enable ALL HTML

thats what I got right now

$AllowableHTML = array("b"=>1,"i"=>1,"strike"=>1,"div"=>2,"u"=>1,"a "=>2,"em"=>1,"br"=>1,"strong"=>1,"blockquote"=>1," tt"=>1,"li"=>1,"ol"=>1,"ul"=>1);


what else do I need?
