Only Shortcode Shows on Blog

I successfully installed the plugin, created a slideshow, and inserted the shortcode in a blog; however, on the shortcode shows on the site. Any ideas why that might occur? For reference, here’s a link to the blog: http://perfectimprints.com/blog/hot-new-products/.

Any help would be appreciated.
