Django {{ MEDIA_URL }} blank @DEPRECATED

You need to add the RequestContext in your render_to_response for the context processors to be processed.

In your case:

from django.template.context import RequestContext

context = {'latest': p}
render_to_response('Question/latest.html',
                   context_instance=RequestContext(request, context))

From the docs:

context_instance

The context instance to render the template with. By default, the template will be rendered with a Context instance (filled with values from dictionary). If you need to use context processors, render the template with a RequestContext instance instead.

Adding media template context processor also gets the job done

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.core.context_processors.request",
    "django.contrib.auth.context_processors.auth",
    "django.core.context_processors.media",
    "django.core.context_processors.static",
)

You can also use direct_to_template:

from django.views.generic.simple import direct_to_template
...
return direct_to_template(request, 'Question/latest.html', {'latest': p})

In addition to question provided above can suggest you to take a look at photologue application. It could help you to avoid direct links in template files and use objects instead. F.ex.:

<img src="{{ artist.photo.get_face_photo_url }}" alt="{{ artist.photo.title }}"/>

Update: For Django 1.10 users, the both media and static context processors are already moved in django.template from django.core read the following article for more info: https://docs.djangoproject.com/en/1.10/ref/templates/api/#django-template-context-processors-media
