title: How can show image on submit button?
body: <p><br />
  I have a submit button and I want to show an image(a.jpg) on that button and won't show the value of submit button. Is it possible in case of a 'submit' type button ? (not "type='image'")</p>
  
  <pre><code>&lt;input type="submit" value="submit" /&gt;
  </code></pre>
  
  <p>-Thanks.</p>
