title: change image link when hover the link css
body: <p>I have this link : </p>
  
  <pre><code>&lt;a href = "" &gt;&lt;img src="images_cartographie/cartographie3_05.gif" width="207" height="47" alt=""&gt;&lt;/a&gt;&lt;/td&gt;
  </code></pre>
  
  <p>and I  want to change the image when the user over the link I tested : </p>
  
  <pre><code>#planification:hover{
  background-image:"images_cartographie/cartographie3_03.gif";
  }
  </code></pre>
  
  <p>but the image doesn't change, it is ignored, (I tested background-color it works (then the problem isn't in url or ...))</p>
  
  <p>when I use the background-image without hover like that : 
  it doesn't appear : </p>
  
  <pre><code>#planification{
  background-image:"images_cartographie/cartographie3_03.gif";
  }
  </code></pre>
  
  <p>NB : I generated the page with photoshop</p>
  
  <p>do you have any idea</p>
