Center Logo

With the logo and banner I have now, it looks nice and centered. But, when I go to change the logo to this picture, it won't center up. http://www.BrewReviewCrew.com/wp-content/uploads/2014/04/shirtpossible2000_clipped_rev_1.png I'd love a way to have a 200x200 image of that ^^ be in the center of our header. Can this be done? Thanks! Cory Site: www.brewreviewcrew.com
