This is probably an easy fix but I am not a developer so I'm having a little trouble figuring this out. I have a website in Joomla that is using a jquery slideshow on the home page.
If you see the splash screen, answer "yes" to the "Are you 21" question to get to the home page.

On the home page you'll see the slideshow with the 4 navigation buttons. I know how to replace and edit these pictures. What I want to do however is add 4 more graphics so there are a total of 8. If I add an additional slide to the slideshow it does not increase the navigation automatically.

So, how do I update the slideshow to accommodate 8 pictures?

Also, I'd like to center the navigation on that image. How do I do that?
