why Html form mail gives the coordinates of the image button in firefox

I have a html mail form and I was just wondering why I get the coordinates of the submit image button in the body of the message in firefox, is there a way to delete that.

thanks

 <form me开发者_高级运维thod="post" action="mailto:miles@faithinstyle.co.uk?subject=Password Request enctype="text/plain">
            <input type="image" id="email_button" src="images/buttons/here.png">
</form>

You can do something like this:

<a href="mailto:miles@faithinstyle.co.uk?subject=Password Request">
    <img id="email_button" src="images/buttons/here.png" />
</a>

either don't use input type=image or just ignore the data. what problem are you trying to solve?
