title: input type=image name and value not being sent by ie and opera
body: <p>When a form has multiple image inputs and the server side uses their <em>names</em> and/or <em>values</em> to distinguish which one was clicked, it works perfectly in FireFox. However, people often write the whole thing before finding out that HTML specifies that nothing has to be sent, and thus some browsers are not sending it. </p>
  
  <p>It's not about sending any random object, but sending a pair as <code>input_name=input_value</code>. The best worst-case scenario example here would be what I've encountered: A list of elements all in one form and all accompanied by buttons with <code>name="delete" value="&lt;item_id&gt;"</code> </p>
  
  <p>What can I do to fix this problem?</p>
