title: Input type image is not working in firefox
body: <p>I have some problem.
  Firefox can't read the value and name of input type image.</p>
  
  <p>Here is my piece of code:</p>
  
  <p><strong>*blabla.php</strong></p>
  
  <pre><code>&lt;?php
  echo"
  &lt;form action='cek.php' method='POST'&gt;
  &lt;input type='image' src='something.png' alt='Submit button' value='Continue' name='noi'&gt;
  &lt;/form&gt;
  ";
  ?&gt;
  </code></pre>
  
  <p><strong>*cek.php</strong></p>
  
  <pre><code>&lt;?php
  echo"
  $a = $_POST['noi'];
  &lt;input type='text' value='$a'&gt;
  ";
  ?&gt;
  </code></pre>
  
  <p>but Firefox says there is no input named 'noi'.
  Please help me to solve this problem.</p>
  
  <p>Thanks in advance.</p>
