Mantra Theme: Can't get Image Slider to work on Presentation Page

I have recently installed the Mantra theme on my site http://www.thegreatsouthernbrainfart.com. I love it but I cannot get images to show up in the slider. I tried uploading photos to the wp-content/themes/mantra/images/slider folder and still nothing shows up at all.

I have the slider set up to load latest posts. Everything seems to work except for the fact that no images show up.

Any help on this is GRATELY appreciated and if you’re in the Atlanta area, I’ll buy you a beer or three as a thank you 😉
