Best way to get more than one value form Json?

I'm using bootstrap for my website, and in the center I need to display a series of item names with pictures. The name information I get form a Json that I request from a URL.

This is what the Json looks like

{
   "success": true,
   "rgInventory": {
      "3019159034": {
         "id": "3019159034",

         "instanceid": "302028390",
         "amount": "1",
         "pos": 1
      },
      "3007405356": {
         "id": "3007405356",
         "classid": "520025252",
         "instanceid": "0",
         "amount": "1",
         "pos": 2
      }
   },

               "category_name": "Category"
            },
            {
               "internal_name": "Rarity_Common_Weapon",
               "name": "Consumer Grade",
               "category": "Rarity",
               "color": "b0c3d9",
               "category_name": "Quality"
            },
            {
               "internal_name": "WearCategory2",
               "name": "Field-Tested",
               "category": "Exterior",
               "category_name": "Exterior"
            }
         ]
      },
   "more": false,
   "more_start": false
}

And yes I'm trying to display my CS:GO inventory.

In short: what is the best way to get the market_hash_name value from the Json? and make it display a image?
