nginx/django file download permission - django

Question

i have a django website running on ubuntu nginx where a user can upload image and another user can download the image.
Problem is when i upload image from frontend then another user can view the image but can't download the original image and when i upload the image from backend its downloadable.
i need to change file permission every time to download the image
