Ok first go to your admincp and selectt the styles & templates button on the left. there in the scrolling section. Next click on the option title style manager. Bow a new page will load in the center display shwoing all your skins. Next you would click the go button next to the dropdown list that is to the far right of your skins name. By default the list says all style options. This will open a new page in the center area with your header header include and footer template being displayed. Scroll to the near bottom and find a textarea with a title called additional css definitions. Add that to the bottom of the list. Be sure to have the id or class name.

If its an id it would be

#idname { background-image: url (images/misc/mypic.gif); }

or a class it would be

.classname { background-image: url (images/misc/mypic.gif); }

Please tell me what it is your trying to do are you making a new header image or changing a catagories color?
