Centering Small Image Displays in a folder

http://www.tomdphotos.com/customize/PhotoGalleriesI/AirShows/AS0510/2006 This is a folder display page that has 6 galleries displayed. Is CSS available to center the displays? I am not worried about having two rows displayed, but am concerned about galleries center displaying when there are only 1 or two galleries in a folder. Thank you for your assistance!
