Answer 1

you can change photo size after save the data using 'Pillow' , for example i am going to change the user profile image to 300 x 300 :

1-first make sure 'Pillow' is installed .

2- here is my code :

from PIL import Image

class Profile(models.Model):
    user_group_rule_options = [
        ('site_manager', 'site_manager'),
        ('site_sales', 'site_sales'),
        ('site_technical_support', 'site_technical_support'),
        ('site_user', 'site_user'),
    ]

    PRF_user = models.OneToOneField(User, on_delete=models.CASCADE)
    PRF_user_group = models.CharField(max_length=30, choices=user_group_rule_options, default='site_user')
    PRF_image = models.ImageField(upload_to='profile_img', blank=True, null=True)
    PRF_country = CountryField()
    PRF_address = models.CharField(max_length=100)
    PRF_join_date = models.DateTimeField(auto_now_add=True)
    PRF_slug = models.SlugField(blank=True, null=True)



    def save(self , *args , **kwargs):
        # change profile image size
        img = Image.open(self.PRF_image.path)
        if img.width > 300 or img.height > 300:
            output_size = (300, 300)
            img.thumbnail(output_size)
            img.save(self.PRF_image.path)
