title: Django Uploaded images not displayed in development
body: <p>I have defined a model with a 'pic' image field:</p>
  
  <pre><code>class Photo(models.Model):
      title = models.CharField(max_length=100)
      body = models.TextField()
      teaser = models.TextField('teaser', blank=True)
      pic = models.ImageField(upload_to = 'pic_folder/', default = 'pic_folder/None/default.jpg')
      created=models.DateTimeField(default=datetime.datetime.now)
      pub_date=models.DateTimeField(default=datetime.datetime.now)
      categories = models.ManyToManyField(Category, blank=True)
      likes = models.IntegerField(default=0)
      dislikes = models.IntegerField(default=0)
      visits = models.IntegerField(default=0)
      slug = models.CharField(max_length=100,  unique=True, blank=True)
  </code></pre>
  
  <p>And here is the upload form:</p>
  
  <pre><code>class PhotoForm(forms.ModelForm):       
  
      class Meta:
              model= Photo
              fields = ( 'title', 'pic','body', 'categories') 
  </code></pre>
  
  <p>Wich post to this view:</p>
  
  <pre><code>@staff_member_required
  def add_photo(request):
      if request.method == 'POST':
          form = PhotoForm(request.POST, request.FILES)
          if form.is_valid():
              form.save()
              messages.info(request, "photo was added") 
              return render(request, 'home.html')
          else:
              messages.info(request, 'form not valid')
              return render(request, 'home.html')
  
      if request.method == 'GET':
          form = PhotoForm()
          args = {}
          args.update(csrf(request))
          args['form'] = form
          return render(request, 'photo/add_photo.html', args)  
  </code></pre>
  
  <p>The problem is that while photo objects are being saved and the file uploaded but the images are not displayed. </p>
  
  <pre><code>  &lt;div class="photo_body"&gt;&lt;img src="pic_folder/someimage.jpg" &gt;&lt;/div&gt;
  </code></pre>
  
  <p>I also set </p>
  
  <pre><code>MEDIA_ROOT = '/path/to/my_project/pic_folder'
  </code></pre>
  
  <p>and run manage.py collectstatic, but they did not solve the problem.</p>
  
  <p>I really got confused about this. So appreciate your hints. </p>
