Graphic Toggle buttons
To change a text Toggle Button into a graphic Toggle Button, open the settings for the Toggle Button and do the following: 
1.	Set the Label type to Graphic. 
2.	Specify the graphic descriptor information. 
3.	Set the Indicator type to on to have a regular check box or off to have a Toggle Button. Off is best for graphic toggle buttons. 
A little extra space is added around the button, so you must resize the button to keep it the same size as the other buttons.
