Portfolio not appearing

I have a page set up to pull a few different categories of portfolio items. If you nav to http://shanetucker.com/photography/ you will see the “shireman family” portfolio item (I’ve not loaded any more items to this page yet). I can’t seem to figure out how to get the images to load to this portfolio item. I have loaded “preview images” to the “Edit Portfolio Entry” page but nothing is appearing on the link I mentioned above. How do I get images to show up for preview on that page, and how do I add the additional images (not in the preview) to that portfolio?
