Title: Add a warning about the usage of ng-src

The example is confusing and lead to incorrect usage of ng-src. In development, you may get a DirectoryListing when fetching a resource without the `hash`, but in production if DirectoryListing is disabled, you get a 404.
By adding the warning, the user will be aware of the implication of ng-src.
