The CreateModelMixin of the CreateAPIView calls the serializer listed. Therefore, you need to serialize and validate the image inside the AnnouncementSerializer using the PhotoSerializer. This can be done by overriding the create method of the AnnouncementSerializer:

class AnnouncementSerializer(serializers.ModelSerializer):
    parameters = ParameterSerializer(many=True, required=False)
    photo = PhotoSerializer(
                many=True, 
                required=False, 
                read_only=True) # Set read_only to True

    class Meta:
        model = Announcement
        fields = ['id', 'name', 'address', 'date',
                  'price', 'description', 'author', 'parameters', 'photo']

    def create(self, validated_data):
        """
        Serializes an image if it has been uploaded, then passes the image
        back to the validated_data to finish creating the Announcement.
        """
        image_data = self.context['request'].FILES
        if image_data:
            serializer = PhotoSerializer(data=image_data)
            serializer.is_valid(raise_exception=True)
            image = serializer.save()
            validated_data['image'] = image
        return super().create(validated_data)

That should be all you have to do.
