Hi,

Ok, so what you should do is add a signal to pre save and then delete the old image if the new image is attached.

Something like this should work:

from django.core.files.storage import default_storage as storage
from django.db.models.signals import pre_save

def image_delete(sender, instance, *args, **kwargs):
if instance.pk:
old_instance = User.objects.get(pk=instance.pk)

if old_instance.image != instance.image and instance.image:
storage.delete(old_instance.image.name)

pre_save.connect(image_delete, sender=User)

You can see more information about signals here: https://docs.djangoproject.com/en/1.7/topics/signals/

Andréas
