Django REST Framework, image breaks on uploading

Question

I have model Product:

class Product(models.Model):
    ...
    image = models.ImageField(
        upload_to=lambda instance, filename: 'images/{0}/{1}'.format(instance.id, filename),
        max_length=254, blank=True, null=True
    )
    ...

Then I have serializer:

class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = (
            ...
            'image',
            ...
        )

And then I have views:

class ProductViewSet(BaseViewSet, viewsets.ModelViewSet):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer
    @detail_route(methods=['POST'])

    def upload_image(self, request, *args, **kwargs):
        upload = request.data['file']
        print(upload.name)
        product = self.get_object()
        product.image.delete()

        upload = request.data['file']
        product.image.save(upload.name, upload)

        return Response({'Location': product.image.url}, status=status.HTTP_201_CREATED)

Problem is only with images. On uploading images changes 'source code', and I can't open it, in the browser black window. Mp3 and PDF formats works fine. Why does it happens? Thank you.

Maybe the problem is with base64 images? In this case you should import ModelSerializer from drf_base64.serializers and inherit from that.

problem was with parser, I used FileUploadParser instead of MultiPartParser :) Thank you!
