Bilder in Dropdown

[aa]

Wie kann ich denn dieses

<!--

option[value=deutschland]:before { content:url("de.gif"); }
    option[value=irland]:before { content:url("ie.gif"); }

-->

Variable machen?

$select = ("SELECT name,url FROM images");  
   $query = mysql_query($select);  
   while ($ds = mysql_fetch_object($query)) {  
                        $name = $ds -> name;  
   $url = $ds -> url;  
   echo "option[value='$name']:before { content:url('"$url'"); }

So?
