django.db.models ImageField Python Code Examples

ImageField (documentation) is a Django ORM field-to-column mapping for storing image files in a Django application. This field is a subclass of FileField so it has all of the attributes of that class, as well as a couple of new optional attributes, height_field and width_field, to make it easier to query the stored image data.

ImageField is defined within the django.db.models.fields module but is typically referenced from django.db.models rather than including the fields module reference.
