<input type="image" src="login_button.png" name="login" /> Error in IE !! HELP

[2939195631902]

<input type="image" src="login_button.png" name="login" /> this will show up as NOT set in IE, but SET in Chrome. It will only show SET in IE, if i change type into type="submit" rather than "image".

These two piece of codes is from my website. I put them on test.php and test_action.php in attempt to figure out the problem.

test.php:

<form action="test_action.php" method="post">
<input type="image" src="direct_images/header_login_button.png" name="login" />
</form>

In test_action.php the only thing is:

if (isset($_POST['login'])) {
echo "login is set";
} else {
echo "error";
}


Yet, it says "login is set" for chrome, but says "error" in IE. However, if i change the type="image" into type="submit", it works fine in both.

I'm sure you'd get the same result if you try it on your wamp.

any comment is apprecaited.!!
