[Plugin: NextGEN Gallery] Social Media Buttons & Thickbox.css customizing

There are several plugins available to integrate social mediabuttons with pages & posts.
However there are none that add social media buttons (for example: Facebook Like/Share) to individual photographs.
I’d love such a feature.

Does anyone know of such a plugin?
Or how to integrate for examle “Share and Follow”

Also I’d like to know how I can customize the Thickbox.css.
I’d like a black background instead of the default white.
