     = ???

I would not have a separate "button tag" for each button in the AS clause.
How could you handle the button click event? In the example we set the
button tag property to unique value. Then use LAST.Tag object to see which
button was pressed. Look at example to see how we handle the click event.

or plain:

  bh.picture = Picture["MyImage.png"]
