I'm using Django to create a stock photo site, I have an ImageField in my model, the problem is that when the user updates the image field, the original image file isn't deleted from the hard disk.
How can I delete the old images after an update?
You'll have to delete the old image manually.
The absolute path to the image is stored in your_image_field.path. So you'd do something like:
os.remove(your_image_field.path)
But, as a convenience, you can use the associated FieldFile object, which gives easy access to the underlying file, as well as providing a few convenience methods. See http://docs.djangoproject.com/en/dev/ref/models/fields/#filefield-and-fieldfile
