Having switched from the "Benevolence" theme to the "Bricks" theme I've discovered that these themes use the body background differently.
The "Benevolence" theme used a background image that displayed along the sides of the blogging page and wrappers to change the images for the sidebars, etc.
The "Bricks" theme uses a background image for displaying the columns within the page itself. You can change the background "color" and that changes the sides but you can't display a background image that appears on the sides.
Does anyone know how I can add a background image that will display on the sides of the page and not change the way the page itself looks?
