I've been betting for an hour, but apparently I don't understand something. There is a task to write a scraper with the django admin panel and everything is fine and works here. Now i need to save all the data to the database and here is the problem, only one photo appears in the django admin panel, but everything is downloaded in the media folder.

# models.py
from django.db import models


class Apartment(models.Model):
    rooms = models.CharField('кол-во комнат', max_length=64)
    price = models.CharField('цена', max_length=10)
    address = models.CharField('Адрес', max_length=256)
    desc = models.TextField('описание')
    floor = models.CharField('этаж', max_length=5)

    def __str__(self):
        return self.address

    class Meta:
        verbose_name = 'квартира'
        verbose_name_plural = 'квартиры'


class Image(models.Model):
    apartment = models.ForeignKey(Apartment, on_delete=models.CASCADE)
    img = models.ImageField(upload_to='media/')

    class Meta:
        verbose_name = 'фото'
        verbose_name_plural = 'фото'


class Url(models.Model):
    created = models.DateTimeField(auto_now_add=True)
    url = models.URLField('ссылка')

    def __str__(self):
        return self.url

    class Meta:
        verbose_name = 'ссылка'
        verbose_name_plural = 'ссылки'
        ordering = ['-created']

#scraper
@receiver(post_save, sender=Url)
def saved_url(instance, created, **kwargs):
    apartments = []

    if created:
        url = instance.url
        soup = make_request(url)
        for link in soup.find_all('div', attrs={'data-name': 'LinkArea'}):
            url = link.find('a').get('href')
            driver.get(url)
            time.sleep(1)
            try:
