Image in sliding menu

[wxdqz]

I need to add images to the sliding menu that I used here. <!-- m --><a class="postlink" href="http://www.infinitypages.com/menu">http://www.infinitypages.com/menu</a><!-- m --> I want to add an arrow that points down for the links that have sublinks. The external JavaScript code can be found at <!-- m --><a class="postlink" href="http://www.infinitypages.com/menu/menu/sliding_menu.js">http://www.infinitypages.com/menu/menu/sliding_menu.js</a><!-- m --> If anyone know how I can do this, I'd appreciate the help. Thanks.
