Dynamic gallery attached to post

I have a blog with a permalink structure like http://www.example.org/actor/matt-damon. I have gallery assigned to the post (I modified the plugin) which is displayed in the sidebar. I would like the widget thumbs to redirect to the gallery at http://www.example.org/actor/matt-damon/gallery/image-2 for instance. My goal is to not use any shutter/lightbox and use the carousel feature.

I’m having a difficult time mapping the extra “/gallery” to a page that would be able to connect the gallery to the post, making it dynamic without using any Custom Fields.

Any suggestions?

Thanks!
