  <pre><code>class Photo(models.Model):
      pub_date = models.DateTimeField('date published')
      sort = models.IntegerField()
      photo_category = models.ForeignKey(Photocategory)
      title = models.CharField(max_length=200)
      title_url = models.SlugField(max_length=200)
      main_image = models.ImageField(blank=True, null=True, upload_to='images/photo/')
      # size is "width x height"
      cropping = ImageRatioField('main_image', '350x350')
  
      def image_thumbnail(self):
         return '&lt;a href="/media/%s" target="_blank"&gt;&lt;img width="160px" src="/media/%s"/&gt;&lt;/a&gt;' % (self.main_image, self.main_image)
  
      image_thumbnail.allow_tags = True
      image_thumbnail.short_description = 'main_image'
  
      def __unicode__(self):
          return self.title
  </code></pre>
  
  <p>admin.py</p>
  
  <pre><code>class PhotoAdmin(ImageCroppingMixin, admin.ModelAdmin):
  
      prepopulated_fields = {'title_url': ('title',)}
      list_display = ('title', 'photo_category', 'image_thumbnail', 'sort')
      list_filter = ['photo_category']
      admin.site.register(Photo, PhotoAdmin)
  </code></pre>

  <p>Is there a way I could do lets say 5 at a time on the 1 screen, it is very slow filling that out 1 by 1. I can do it in mysql with SQL query but I would like to achieve this here.</p>
  
  <p>Thanks</p>
