Change Google +1 Button to Square Image?

Anyone know how to change the appearance of the google plus one button to a square?

It is not in the default developer settings. I am at a loss with this one. It needs to be changed to a square to fit in with the rest of my site. http://borealtrek.com Thanks for the help.
