The most direct method is overriding the model's save() method. Every time a picture instance is saved, it will go through whatever you put in the save method -- usually this means using the PIL library, which may or may not be installed in your production environment. Use the PIL.Image class to open the image (ie img = Image.open(self.imagefield.path)) and manipulate it, then resave it. Check out both PIL: http://www.pythonware.com/products/pil/ and the django file storage docs: http://docs.djangoproject.com/en/dev/ref/models/fields/#imagefield Note that changing the path to something relative to the currently logged-in user will be a little more difficult. As far as I know the thread-locals hack is still required there...
