extending the django admin site

[alexander lind]

How do I add a custom field to the a model rendered as a form by  
django admin site?

My model has a 'choices' field with 4 possible choices: png, gif, jpg  
and 'none'.  As you can guess this describes the format of an image.  
What I want to do is get the admin site to display a file upload  
widget, and I then want to manually process the uploaded image, save  
it in special way, and set the choices field accordingly.

Can someone please tell me how I can accomplish this?

I have read the django admin site manual, but it has nothing on this  
kind of customization, which I must assume is not all that uncommon.

Thanks
Alec
