Form Image As Button : Not Working

[Cooper94]

I have created a html form that when the image is pressed it will echo somthing out. But the code that is below seems to not work for what ever reason. I thank you all for your help and for your time!

 

<form action="" method="POST">
<center>
<table>
<tr>
<td>Callsign:</td> <td><input type="text" name="username" value="RPA" size="10" style="width: 79px;" /></td>
</tr>

<tr>
<td>Password:</td> <td><input type="password" name="password" size="10" max-size="5" /></td>
</tr>

<tr>
<td><input name="login" type="image" src="images/login.png" width="58" height="20"></td>
</tr>
</table>
</center>
</form>


<?php 
if(isset($_POST['login'])) { 
echo "lol";

}
?>

Images as submit buttons send the x,y coordinates where they were clicked on, per the W3.org specification. See this link how that can be accessed in php code - http://us3.php.net/manual/en/faq.html.php#faq.html.form-image
