Change submit image src

[papa_face]

Hello,
How do I change the src of this submit button when it is clicked?

<form action="file.php" method="post" name="links">
<input name="url" type="text" class="downloadurl" />
<input type="image" id="downloadbutton" src="imgs/download.gif" value="Download" name="submitbutton" alt="Submit">
</form>

Any help would be appreciated.

regards

Got this figured out thanks.

I understand the the conventional window.stop(); doesnt work in IE, and I have heard that invoking the key code 27 for escape will stop the page.

How can I make that happen?
