Issues with recent accordion

Hey i recently bought xenforo and i have just finished installing xenporta. I am trying to get an image slider to work on the homepage of my site, but the images will not show. i have recentnews pointing to the right forum i can see it displayed on the homepage. I also have an image named "slider.png" attached to it yet nothing gets displayed. Anyone have any idea whats wrong? Here is a pic.
I also changed the details of the picture that the slider loks for, it now looks for "slider.png" not "slide.jpg"
