Having issues with the slideshow

I am trying to make the slider show work on the front page of my site using the Pinboard theme. I have followed the directions I had and created sticky posts with the images. Nowm I am seeing the markers (little white dots) and the slideshow buttons on the front page, but the images themselves are not showing up.

Am I missing a step? Has anyone got any tips on making the slideshow feature work?

I have screenshots available but cannot make the site public to show, as it is for a school. Thanks for any help!
