sorl-thumbnail's template tags do nothing

I'm using sorl-thumbnail to get some images to crop.

I have a model looking like this

from django.db import models
from sorl.thumbnail import ImageField

class Photo(models.Model):
    image = models.ImageField(upload_to="uploads")

and inside my template I have

{% load thumbnail %}

{% thumbnail photo.image "200x100" as im %}
    <img src="{{ im.url }}">
{% endthumbnail %}

This doesn't output anything. If i do <img src='{{photo.image.url}}'> the image displays fine within the browser. I also have sorl-thumbnail inside my INSTALLED_APPS and I sync'd the database and have the thumbnail_kvstore table setup.

Can someone help me please. What could cause the images to not be cropped or even displayed?

Your code looks fine, so the problem should come from other parts.

The first thing you can do is to set THUMBNAIL_DEBUG = True in your settings.py and see why the error occurs.

Are you using virualenv and PIL for image library? Make sure your PIL is compiled and installed with jpeg and png/gif support which requires libjpeg and zlib.

Edit: As @DanielRoseman pointed out in the comment, you are actually using django.db.models.ImageField, changing 

image = models.ImageField(upload_to="uploads")

to

image = ImageField(upload_to="uploads")

to use sorl.thumbnail.ImageField instead.

Try doing a cleanup, or if that fails, clear. Documentation

This resolved the problem for me when I was getting unexpected output. Maybe it will work for you.
