I can't seem to get the Buy Buttons to Appear

I'm using NextGen Gallery with NextGen Pro Version 2.1.4 on WordPress 4.1 with the latest Big Gallery WP theme. For galleries in NextGen I've tried Fancybox, Thickbox and can't get the buy buttons to appear. Website URL is https://www.markkosinski.com. Any help would be really appreciated!!!
