Как добавить обложку к книге?

class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)
    publisher = models.ForeignKey(Publisher)
    publication_date = models.DateField()
    num_pages = models.IntegerField(blank=True, null=True)
    image = models.FilePathField(path="/static/img/books/", match=".jpg$, .gif$, .png$, .jpeg$", 
                                 recursive=True, allow_folders=True, blank=True, null=True, max_length=100)
    
    objects = models.Manager() #Book.objects.all() - все книги
    dahl_objects = DahlManager() #Book.dahl_objects.all() - книги написанные Роальдом Далем
    
    def __unicode__(self):
        return self.title
    
    class Meta:
        ordering = ['title']

image2 = models.ImageField(upload_to='/static/img/books/', blank=True, null=True)

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'

image = models.ImageField(upload_to='img/books', blank=True, null=True)
