将图像字段添加到模型

Question

我想将ImageField添加到我的模型名称"models"中，但是管理面板失败了.... 我是初学者...我的失败是我知道的非常基本的例外，但我无法解决。

我该怎么办？ (对不起，我的英语不好，我是高中生(

型号代码

from django.db import models
# Create your models here.
#create a model and some models
class posting (models.Model):
title=models.CharField(max_length=120,verbose_name='Başlık')
content=models.TextField(verbose_name="İçerik")
publishing_date=models.DateTimeField(verbose_name="Yayınlanma tarihi")
