Get More Details Question

I just downloaded this theme and am looking around the different features. On the Image Show, there is a button saying "Get More Details". I can't figure out how to edit where they point when clicking on them. Right now, it doesn't do anything and I can't find it in the widgets area.

Thanks!

edit your slides in Media Library and change The “Alternative Text” field to change the URL.

Thank you
