sorry, change the label of the second button to "swap background":<input type="button" value="swap background" onclick="img = mytable.rows[0].cells[0].style.backgroundImage;mytable.rows[0].cells[0].style.backgroundImage=mytable.rows[0].cells[1].style.backgroundImage;mytable.rows[0].cells[1].style.backgroundImage=img;">
