Hi all! I've installed the Categories Dressing mod successfully, but have a slight problem with where I put the images I use to display the category links. By default, they are in the 'images' directory and the path is specified in the stylesheet e.g.

a.catBg79 {
background-image: url(../images/catbg79.gif);
height: 22px;
}

This works fine, but as I have quite a few of these images I wanted to tidy things up a bit and put them into their own sub-directory:

a.catBg79 {
background-image: url(../images/categorybuttons/catbg79.gif);
height: 22px;
}

For some reason when I do this the images will not display. I've looked for clues in tpl_categories.php but cannot figure it out.
