Resources Pack Picture

is it possible to add a resources pack picture? how?
i use:

Code:

{
  "format_version": 1,
  "header": {
    "description": "---------------------------------",
    "name": "Philippine WellPlayed Server",
    "uuid": "---------------------",
    "version": [2, 0, 0]
  },
  "modules": [
    {
      "description": "---------------------------",
      "type": "--------------------------",
      "uuid": "-------------------------------",
      "version": [2, 0, 0]
    }
  ]
}

 

Place the 64px×64px pack_icon.png in the root folder of the resource pack
