Delete django images on heroku?

Question

Django

After executing the commands:
git add -a
git commit -m 'asd'
git push heroku master
And all the entries (which I have already made on the flooded site) lose pictures.
I changed many settings in settings.py but all without success

settings.py:

"""

Heroku does not store the state of its containers, so if you want to store something from downloads, then you need to do it on some other service
