How to remove links in the slider?

Is there a way to remove the links on the images in the slider? My images are banner ads that lead to empty posts. 🙁 I have the slider posts hidden from other areas of the site, but they can still be reached by clicking on the slider.

Here’s my site: http://www.erinholmberg.com/

Ideally, there would be some custom CSS code I could put in the Appearance > Theme Options > Layout > Custom CSS

Thank you!
