The OP clearly doesn't understand why though, see his other thread on
this topic.
Your browser is a careful beast. It won't allow a webpage loaded from
the internet zone to load things from the local zone, as That Would Be
Bad. When you 'double click' the file and 'it works', what is actually
happening is that the webpage is loaded from the local zone, and so
access is allowed.
Also, Django is a web app. This means that most users who use your
site will not be using it from your desktop, so they would not be able
to access files on your local machine. Therefore, you need to provide
a way to serve these files over HTTP, so that other users can access
them. See the link in Daniel's reply on how to do this.
