Hi
It doesn't know what 'image' is in that context.
Actually after inheritance, you have a button with attribute 'image' which
gets value from 'img' attribute if element.
You can get xul:button element via
document.getAnonymousNodes(this)[0]
so, you write something like
document.getAnonymousNodes(this)[0].style.width ='128px';
document.getAnonymousNodes(this)[0].style.height ='128px';
And if you change elements order (now you have only one element) you should
change indexes or get your button with childNodes
