title: Image Path Returning a 404 on Django Admin
body: <p>Whenever I visit the path for an uploaded image in the admin, I get a 404. The image is successfully uploaded in the specified path but I don't know what URL structure to use to access the image. There is not URL structure specified yet for the image (that's what I want to know, or am I missing anything else?). Here are the details:</p>
  
  <p>My models.py</p>
  
  <pre><code>class Product(models.Model):
      category = models.ForeignKey('CatalogCategory', related_name='products')
      name = models.CharField(max_length=300)
      slug = models.SlugField(max_length=150)
      description = models.ImageField(upload_to='product_photo', blank=True)
      manufacturer = models.CharField(max_length=300, blank=True)
      price_in_dollars = models.DecimalField(max_digits=6, decimal_places=2)
  </code></pre>
  
  <p>this is the error:</p>
  
  <blockquote>
    <p>Request
    URL:  <a href="http://localhost:8000/admin/products/product/1/product_photo/soy_candles.jpg/" rel="nofollow">http://localhost:8000/admin/products/product/1/product_photo/soy_candles.jpg/</a>
    product object with primary key
    u'1/product_photo/soy_candles.jpg'
    does not exist.</p>
  </blockquote>
  
  <p>this is the dir struct</p>
  
  <pre><code>product_photo
  products
  -&gt;templates
  -&gt;models.py
  -&gt;views.py
  -&gt;...
  manage.py
  settings.py
  urls.py
  </code></pre>
  
  <p><strong>EDIT</strong>
  I have not touched the details regarding the admin on the settings </p>
