This Module displays an image or loads a CSS-File from your choosen directory depending recursively on the active menu item and the menus structure.

It is usefull for e.g. to simply change header images or the color of article titles. But it can be very powerful too by completely changing the view of your website by adding different style sheets depending on the active menu item without the need of making multiple templates.

All in all not a bad Joomla Extension – there is a very nice icon ads system for Joomla here.
