Nextgen and Simple WordPress Shopping Cart Plugin integration

I have just installed Simple WordPress Shopping Cart Plugin and it works quite well on pages and posts, but doesn’t do anything when I try to use it with Thumbnails in the Gallery.
You can see it, that it gives me only the code under the first thumbnail image, but works on the posts bellow it.
I have put in the :gallery-wp-eStore.php into the Nextgen/view folder.
Here is the link to my site:

Any help is appreciated
