title: Input type image causing confusion
body: <p>I currently have the following code:</p>
  
  <pre><code>&lt;form action="process.php" method="POST"&gt;
  &lt;fieldset class="form-search"&gt;
      &lt;input type="text" class="input-text" name="keyword" value="Enter Keyword / Catalogue Code" id="textBox"/&gt;
      &lt;?php echo $form-&gt;error("keyword"); ?&gt;
      &lt;input type="image" class="catalog_search_top" name="search" alt="Search" src="../images/search_form_button.png" /&gt;
  &lt;/fieldset&gt;
  </code></pre>
  
  <p></p>
  
  <p>My problem is that the image when submitted isn't doing the same as if its image type submit.</p>
  
  <p>When submitting the form with the code I provided, would it be expected that it would go to form process.php and send $_POST['submit']?</p>
  
  <p>Thanks</p>
