ImageField - Django Models

Last Updated : 12 Jul, 2025

ImageField is a specialized version of Django's FileField designed to handle image uploads. It restricts uploads to image formats and provides additional attributes for storing image dimensions.

Install Pillow with:

pip install Pillow

Syntax

field_name = models.ImageField(
upload_to=None,
height_field=None,
width_field=None,
max_length=100,
**options
)

Key Arguments for ImageField Argument Description instance An instance of the model where the ImageField is defined. More specifically, this is a particular instance where the current file is being attached. filename The filename that was originally given to the file. This may or may not be taken into account when determining the final destination path

For example:

Python 
def user_directory_path(instance, filename):

    # file will be uploaded to MEDIA_ROOT / user_<id>/<filename>
    return 'user_{0}/{1}'.format(instance.user.id, filename)

class MyModel(models.Model):
    upload = models.ImageField(upload_to = user_directory_path)
height_field and width_field

Names of model fields (usually IntegerFields) that will be automatically populated with the height and width of the uploaded image whenever the model instance is saved.

Example: Using ImageField in a Model

Assuming a Django project geeksforgeeks with an app geeks:

Refer to the following articles to check how to create a project and an app in Django.

Enter the following code into models.py file of geeks app.

Python 
from django.db import models
from django.db.models import Model

class GeeksModel(Model):
    geeks_field = models.ImageField()
Setup and Migration

1. Add your app to INSTALLED_APPS in settings.py:

Python 
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'geeks',
]

2. Run migrations:

Python manage.py makemigrations
python manage.py migrate

Using ImageField with Django Admin

1. Create a superuser to access the admin interface:

python manage.py createsuperuser

2. Run the development server and log in to the admin:

http://localhost:8000/admin/

3. Add new instances of your model and upload images via the admin panel.

Go to add in front of Geeks Models.

Choose the file you want to upload and click on save. Now let's check it in admin server. We have created an instance of GeeksModel.

Field Options for ImageField

Field Options are the arguments given to each field for applying some constraint or imparting a particular characteristic to a particular Field. For example, adding an argument null = True to ImageField will enable it to store empty values for that table in relational database. Here are the field options and attributes that an ImageField can use.

Field Options Description Null If True, Django will store empty values as NULL in the database. Default is False. Blank If True, the field is allowed to be blank. Default is False. db_column The name of the database column to use for this field. If this isn’t given, Django will use the field’s name. Default The default value for the field. This can be a value or a callable object. If callable it will be called every time a new object is created. help_text Extra “help” text to be displayed with the form widget. It’s useful for documentation even if your field isn’t used on a form. primary_key If True, this field is the primary key for the model. editable If False, the field will not be displayed in the admin or any other ModelForm. They are also skipped during model validation. Default is True. error_messages The error_messages argument lets you override the default messages that the field will raise. Pass in a dictionary with keys matching the error messages you want to override. help_text Extra “help” text to be displayed with the form widget. It’s useful for documentation even if your field isn’t used on a form. verbose_name A human-readable name for the field. If the verbose name isn’t given, Django will automatically create it using the field’s attribute name, converting underscores to spaces. validators A list of validators to run for this field. Unique If True, this field must be unique throughout the table.
