Working with Woocommerce Product pages

Hi,
I like the look of Nextgen Fancybox on gallery pages, and would like to make it work with WooCommerce Product pages – But its opening the product images as single images rather than a gallery.

I thought it might be as easy as just unticking “Enable Lightbox for product images” in woo commerce settings and ticking “try to apply to all images” in Nextgen settings – BUT it doesn’t work.

It opens the images all right – but can’t click from one to the other, nor is the description appearing.

Does anybody know the settings that make this possible? Or can point me to a tutorial that would indicate how I can do it.

Thanks in advance
