In our development setup, we use Zinc’s ZnZincStaticServerAdaptor to serve the external js, css, … files directly from the image.
From what I understand, this is maybe what you are looking for?
I believe all info you need is in the Pharo books that explain Zinc. I don’t have any reusable code to share directly as our dev setup is specific.
There used to be a WAExternalFileLibrary for Seaside 3.0 that allowed to serve the files residing externally to the image but it’s use case is now covered by Zinc.

Your Smalltalk image will surely break down when somebody asks for those files a couple of hundred times a second. I'd rather have nginx or Apache handle the 404 stuff for these situations...
