[html] How to add images in select list?

UPDATE: As of 2018, this seems to work now. Tested in Chrome, Firefox, IE and Edge

UPDATE: Yes I changed the background-color, not the image, stop voting me down, showing that you can change style here is still a useful contribution.

<!DOCTYPE html>
<html>
<body>

<style>
select#newlocale option[value="volvo"]   { background-color: powderblue;   }
select#newlocale option[value="opel"]   { background-color: red;   }
select#newlocale option[value="audi"]   { background-color: green;   }
</style> 

<select id="newlocale">
  <option value="volvo"><div >Volvo</div></option>
  <option value="saab">Saab</option>
  <option value="opel">Opel</option>
  <option value="audi">Audi</option>
</select>
  
</body>
