Yours 404s as well :-)  This is because Angular is rewriting the URL and the CI server is not setup to redirect deep URLs!
Try this, which is probably the same at the moment as yours anyway: http://ci.angularjs.org/job/angular.js-pete/181/artifact/build/docs/index.html
These pages are generated on every build.  The CI server watches my github repos and builds and tests on changes.
You can do this locally with `grunt docs` or something.
The relative path can actually just be `img/path.svg', without the `/` at the start.  This works for the links in the navigation menu.
