add this to your style.css file attached to your website.

 #pngIE	{				 
fillter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src=image.png); 
					background-repeat:no-repeat; 
					} 
 
#pngFF{				 
					background-image:url(image.png); 
					background-repeat:no-repeat; 
					}

put this code where you want to have that image.

<?php

$browser = $_SERVER['HTTP_USER_AGENT'];
$version = explode(" ",$browser);

if($version[2] == "MSIE"){
echo 'pngIE';
}
else{
echo 'pngFF';
}

?>

now edit the parts i've marked red.
and remove the parts i've marked yellow. (damn BBC )

this way you can make .png images transparent in IE.
(fun to fix bugs of those HUGE purely commercial companies )
