I am working on a HTML email and have sytles set up for handheld and screen media coded as:

<style type="text/css" MEDIA=handheld>
<!--
    #header {width:700px;height:108px;margin:0px 0px 0px 0px;padding:0px 0px 0px 0px;}
-->
<style type="text/css" MEDIA=screen>
<!--
    #header {width:700px;height:108px;margin:0px 0px 0px 0px;padding:0px 0px 0px 0px;;background-image:url(http://www.sfomag.com/blastemails/Ne.../mf_header.png)}
-->

This works except for emails to Hotmail accounts. Hotmail will remove the url when rendering the html. I would like to wrap an <IMG> with an IF statement if the media descriptor is 'screen'. How can I detect the media descriptor? Or is there another work around for the url?
