models.py
class Banner(models.Model):
banner_photo = models.ImageField(null=True, blank=True)
As the answer below, I would like to preview the image selection before saving the banner image in django-admin. I am a beginner about HTml. How do I override it?
I want to preview the banner picture to be registered with Admin like the captured image. I don't know how to apply it even if I see the answer.
