Having Issues Replacing Image

Having Issues Replacing Image

I'm trying to replace an image.  what am I missing?  
I don't really need to replace it. I can just inject it inside the div ccl-test-from tag as well.

 
<div id="adArea">
<div class=".ccl-test-front">
  <img src="/image/abc.jpg" alt="Smiley face" width="80" height="60">
</div>
 </div>


$("#adArea .ccl-test-front img").attr({"alt":"This is a test!","src":"/image/xyz.jpg"});
