Need Help With Chameleon Child Slider

I am currently trying to change the pictures and information on our slider that were put into place by the company that originally built our site.

I know that the information on it are the titles of the posts on our site but I am hoping to include our daily menu that we provide as well as our daily events. We use the My Calendar for our Menu and the Ajax Event Calendar for our daily events.

I am also struggling with our pictures that are on the slider. They are currently stock photos and I would like to change them to our own. I know they are in the Media center but I cant figure out how they are linked to the slider.

Any help would be greatly appreciated!!
