If images from the default style show up in the alternate styles:

If you find that a stylesheet is picking up graphics from the stylesheet you have set as your forum's default:

If your default stylesheet has images for the background, the catbg, the titlebg, the tabs, and for any other area, you will need to tell those areas in the Alternative stylesheets you use that it is important they do not have a background image.

For each area that you need to do this in add the code to the place in the url for that section where the background image code would normally be. 

background-image: none !important;

For instance if you use an image for the forums background on the default style and your alternate style has no background do:


/* The main body of the entire forum. */
body
{
    background-image: none !important;
    background-color: #E5E5E8;
    margin: 0px;
    padding: 12px 30px 4px 30px;

}
