What does Django do with `MEDIA_ROOT`?
When you creates a model with ImageField or FileField attributes, you should pass the upload_to argument. That is a relative path will be appended to your MEDIA_ROOT path and there will be save and retrieve that files.
What does Django do with MEDIA_ROOT exactly? I never understood it. Since Django itself doesn't serve static media, and you have to set up apache or something similar for it, why does it care in which directory it sits?
