Nextgen add to wp e-commerce cart

I would like a photogallery to sell my pictures that is linked to my wp-ecommerce cart. I’m currently using NextGen but that only gives the add to cart option for Paypall. There is no option to add it to my OWN cart.

I guess that there must be a solution in:
Using img title as Product name
img name (img1234.jpg) as product id
and standard prices. €4 for 15×10, €6 for 20×30 prints..?

i don’t! want to use paypall but my (dutch) “Ideal” payment method that i have implemented in WP-eCommerce already.

i would be very much appreciate any help on this becouse i’ve been searching all over the internet but no-one seems to have to same problem..
