How to POST image of nested serializer using postman django APIVIEW

Question

I know how to post image for normal field (using form-data in postman) but I'm stack when I need to post nested serializer contain an image field.

Serializer.py looks like:

class ProgramSerializer(serializers.ModelSerializer):
    image=ImageSerializer()
    class Meta:
        model = Program
        exclude = ('create_date')
        

class ImageSerializer(serializers.ModelSerializer):
    class Meta:
        model = Image
        field= ('image','name')

views.py :

class program_apiView(APIView):

    def post(self, request):
        parser_classes = [MultiPartParser,FormParser]
        serializer = programSerializer(data= request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(
                serializer.data,
                status = status.HTTP_201_CREATED
            )
