title: Django get resized image from model
body: <p>I want to have method that will give me resized image, if i call this method on object, how can i do this with Pillow?</p>
  
  <p>my model:</p>
  
  <pre><code>class Item(models.Model):
      title = models.CharField(max_length=255, null=True)
      img = models.ImageField()
  
      def __str__(self):
          return self.owner.first_name
  
      def get_image(self):
          image = Image.open(self.img)
          resized_image = image.resize((128, 128))
  
          return resized_image
  </code></pre>
  
  <p>This one always gives me something like that</p>
  
  <pre><code>&lt;PIL.Image.Image image mode=RGB size=128x128 at 0x7F001CF92D30&gt;
  </code></pre>
