Slider for Videos and Photos for Blogs MU

I need to add a slider on the home page of Blogs MU. (I'm using it for WP not as a network and I'm using a static page for the home page but can switch to posts if necessary.) I notice on Widgets settings there are three header areas for widgets, however adding a gallery there has no effect.

Do I need to modify my child theme to add a slider to a static page / posts home page? And any recommended gallery plugins that make it easy for a site owner to add photos and video?

Site is here if it helps:
