%description
Storing images and their thumbnails on S3 is a bit of a clumbsy endeavor with
Django. While this Django app may work with more typical storage backends, it
is intended to accept image uploads, thumbnail them, and upload the original
plus the thumbs to S3. You may then get to the thumbnails in your template
by doing something like:

    <img src="{% thumbnail some_obj.image '80x80' %}" />
    
This automatically assembles the remote S3 URL to retrieve the thumbnail from.
No error checking is done, and several assumptions are made for the sake of
speed.

The primary advantage of django-athumb is that, unlike sorl and others,
thumbnails are generated at the time of user uploading the original image.
Instead of generating thumbs on-demand and making the user wait, we get that
out of the way from the beginning. This leads to a few big benefits:

* We never check for the existence of a file, after the first save/upload. We
  assume it exists, and skip a whole lot of Disk I/O trying to determine that.
  This was horrendously slow on sorl + S3, as it had to hit a remote service
  every time it wanted to know if a thumbnail needed generating.
* Since we define every possible thumbnail in advance via models.py, we have
  a defined set of possible values. They can also be more intelligently named
  than other packages. It is also possible to later add more sizes/thumbs.
* This may be ran on your own hardware with decent speed. Running it on EC2
  makes it just that much faster.
