To take advantage of the MEDIA_URL in the settings.py file for hosting your static media on a separate server, you need to do a little internal work on your templates and some work to make that setting available to the templates.
Inside a template, where you would normally have:
blah blah <img src="/img/foo.jpg" alt="this is a foo"> blah blah..
You would instead insert {{ MEDIA_URL }} so that it would look like:
blah blah <img src="{{ MEDIA_URL }}/img/foo.jpg" alt="this is a foo"> blah blah..
It generally requires a big search and replace the first time you implement it. After that, seeing other references in the templates has been enough to remind me to use {{ MEDIA_URL }} before any static content.
We could pass {{ MEDIA_URL }} in through each view, but since we'll want it throughout the site, it's often easier to set up a simple context processor to do the heavy lifting.
Note: There is a default media context processor since version 1.0. You can access using {{ MEDIA_URL }} in your templates.
Then in the settings.py under TEMPLATE_CONTEXT_PROCESSORS, add:
"django.core.context_processors.media",
If you are still on django 0.96:
Here's a example snippet from a context process:
from django.conf import settings def common(request): return {'MEDIA_URL': settings.MEDIA_URL}
Then in the settings.py under TEMPLATE_CONTEXT_PROCESSORS, we added:
"mysite.context_processors.common",
and from there, the MEDIA_URL in settings.py became available in all templates as {{ MEDIA_URL }}.
