Foren / Cotonti / Skins / Tabber: Get image in "tabbertab"

Im using this tabber in users.details.tpl.

But i cant get a small image to show up in "tabbertab":

<div class="tabber">
     <div class="tabbertab"> <img src="http://www.vot3.in/datas/users/1/car_1.png"> <h2>My Ride</h2>
  <p>
  <table class="cells">

The image should show up right? But it doesnt, why?
