BuddyPress Community image slider

On my new buddypress site, outwithcancer.org, I am trying out the theme, BuddyPress Community . You can see, towards the bottom, the image slider installed, without any images. Two questions: I am failing to find the image slider option that is built into the theme BuddyPress Community (I chose it, but now I don’t know how to unchoose it)

Second question: I do not see how to add images to the slider, nor do I see the slider widget or anything about it in the left hand admin column
