Having to change paths within vendor libraries - Rails Asset Pipeline

What's the best practice for loading third party Javascript libraries (into the asset pipeline) that have references to images and css? My concern is that the libaries internal structure will get changed after loaded into the pipeline. For example:

JS library structure
  - some_js_folder
  - some_css_folder
  - some_image_folder

Will the above structure be maintained or will I need to change the path references in the library itself?

Thanks
