[Plugin: Image Store] Adding image to shopping cart Wheel free spinning

Im not really sure what is going on with the plugin. I believe this is something to do with lightbox and my current theme. As it is now the flow of the photos look great but when i try to add an image to the shopping cart i get the spinning wheel of death! Here is a link to my site for an example. http://aaronrooks.com/galleries/test/photos/
(select a photo and click check out). This plugin is exactly what i have been looking for and i would love for it to work properly.
Im thinking there is something from my theme to the plugin that’s not getting along.
Thanks
