Customize Wordpress NextGen Gallery Plugin

I'd like to customize the WordPress NextGen Gallery plugin, When I click on the thumbnail,? instead of the large image and description that opens on a popup layer, it should rather open in a new page, with the regular site header and footer, and it's own URL. See how it is now the attachment called: [login to view URL] I want that after the product is clicked the page should change as something like the attachment called: [login to view URL] Please give me a price and time frame. tx
