How can I validate image uploads in Django?

You can use Django's built-in validators to check the file type and size. Would you like a code example?

Yes, please provide a code example for validating image uploads.

Sure! You can create a custom validator like this:

from django.core.exceptions import ValidationError
from django.utils.translation import gettext as _

def validate_image(image):
    if image.size > 5 * 1024 * 1024:  # 5 MB limit
        raise ValidationError(_('Image file too large ( > 5MB )'))
    if not image.name.endswith(('.png', '.jpg', '.jpeg')):
        raise ValidationError(_('Unsupported file type.'))

How do I use this validator in my model?

You can use it in your model like this:

from django.db import models

class MyModel(models.Model):
    image = models.ImageField(upload_to='images/', validators=[validate_image])
