Hi Murtuza,

I was just going through code change, and I would suggest one small change.
In the image_mapper.js, export it as default, as it will have only one
export. Then you can use it as imageMapper.default rather than imageMapper.
imageMapper.
Otherwise, looks fine to me. I didn't test though :P
