QuickForm - Creating "real" buttons!

Hi If I want to create the following form using HTML_QuickForm - how should I do it?

    <form>
        <button name="test2" type="button" value="0">Before</button>
    </form>

If I use the button element type I end up with this:

    <form>
        <input name="test1" type="button" value="Before">
    </form>

Which is not what I want - I need the value (0) from the real button element as well as the possibility of putting an image between the <button> tags! Hope you can help me! Cheers, Tommy Ipsen
