Nextgen gallery

Hello

I have looked over many post but i still have an error

i am trying to setup a shop using nextgen gallery the plugin i am using to setup the buttons for the shop is WP Simple Paypal Shopping cart.

the problem i have is within the template when i add the short code i get a white background to my images which i do not want i want the image background to be transparent.

every post i have read says the templates should be stored in
/wp-content/plugins/nextgen-gallery/view/

but i don’t have a view folder i have checked from FTP and and only have

wordpress/wp-content/plugins/nextgen-gallery/products/

which would then lead to
wordpress/wp-content/plugins/nextgen-allery/products/photocrati_nextgen/

and then to wordpress/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/

where there is a lot of folders but not one called view

or
wordpress/wp-content/plugins/nextgen-gallery/pope/
which then goes to
wordpress/wp-content/plugins/nextgen-gallery/pope/lib/

or
wordpress/wp-content/plugins/nextgen-gallery/non_pope/
which does not have any folders within it.

can someone please help me to loc the right folder here that should have the templates.

i just need to be able to edit the template that WP Simple Paypal Shopping cart is using. so that when i use the short code the image shows up correctly.

many Thanks

Lorraine
