I've this site: http://www.princeslick.com/?page_id=28 and that i have installed the nextgen wordpress plugin onto it, the gallery isn't being employed as it will. Why do not such as this: http://wordpress.org/extend/plugins/nextgen-gallery/faq/
The NextGen CSS file isn't being incorporated towards the top of your page, so that your images aren't being styled whatsoever. It ought to be incorporated once the wordpress_mind() function runs. Reinclude that if it's not there, or link the CSS file directly.
