title: change image src onMouseOver
body: <p>HTML: </p>
  
  <pre><code>&lt;span class="btn-cover"&gt;
    &lt;img src="../assets/images/btn_page_back_normal.png"  onmouseover="../assets/images/btn_page_back_normal.png" class="date-left" &gt;
  &lt;/span&gt;
  </code></pre>
  
  <p>I have not been able to give a hover effect on the img tag is working to try to substitute a different image from angular.js.</p>
  
  <p>I like what the problem is because you need the help of others, does not work.</p>
