How do i add a rollover to a paypal button?

[geronimo171]

Hi,

I've added some paypal buy it now buttons to a site which is like the code below:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="#####">
<input type="image" src="http://www.MyWebsite.com/MyPaypalButton.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online.">
<img alt="" border="0" src="https://www.paypal.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>

Is there any way to get this to work as a rollover?
I would normally use an <a href> tag for the rollover but am not sure how i would do this with an input image.

Thanks for any help
