Now that we have our product image field in place and we can store images, let's revisit our JSON response that contains the product data and assume it looks something like this now:

      "id" : 1,
      "name": "TV",
      "number": 341,
      "image": "tv.jpg"
    },
    {
      "id" : 2,
      "name": "VCR",
      "number": 123,
      "image": "vcr.jpg"
    }
  ]
}
