I uploaded an image to the proper folder and it shows on the entire body of the page (www.dangerouscupcakedesigns.com) but I only want it to show in the margins or sidebars. How do I change it so that the body of the middle of the page (behind each blog entry) stays white? Thank you!

GO to the center area options of the theme and set the background color to white. If you need the syntax, check out w3schools.com/css

Thanks much!!
