Just loop through your array:

var arr = [
  {
    "albumId": 1,
    "id": 1,
    "title": "accusamus beatae ad facilis cum similique qui sunt",
    "url": "http://placehold.it/600/92c952",
    "thumbnailUrl": "http://placehold.it/150/92c952"
  },
  {
    "albumId": 1,
    "id": 2,
    "title": "reprehenderit est deserunt velit ipsam",
    "url": "http://placehold.it/600/771796",
    "thumbnailUrl": "http://placehold.it/150/771796"
  },
  {
    "albumId": 1,
    "id": 3,
    "title": "officia porro iure quia iusto qui ipsa ut modi",
    "url": "http://placehold.it/600/24f355",
    "thumbnailUrl": "http://placehold.it/150/24f355"
  }
];

arr.forEach(e => console.log(e.thumbnailUrl));

In case you want to get an array of all thumbnails, use array map:

var arr = [
  {
    "albumId": 1,
    "id": 1,
    "title": "accusamus beatae ad facilis cum similique qui sunt",
    "url": "http://placehold.it/600/92c952",
    "thumbnailUrl": "http://placehold.it/150/92c952"
  },
  {
    "albumId": 1,
    "id": 2,
    "title": "reprehenderit est deserunt velit ipsam",
    "url": "http://placehold.it/600/771796",
    "thumbnailUrl": "http://placehold.it/150/771796"
  },
  {
    "albumId": 1,
    "id": 3,
    "title": "officia porro iure quia iusto qui ipsa ut modi",
    "url": "http://placehold.it/600/24f355",
    "thumbnailUrl": "http://placehold.it/150/24f355"
  }
];

var  thumbnails = arr.map(e => e.thumbnailUrl);
console.log(thumbnails );

How about get an Object { "albumId": 1, "id": 1, "title": "accusamus beatae ad facilis cum similique qui sunt", "url": "http://placehold.it/600/92c952", "thumbnailUrl": "http://placehold.it/150/92c952" }, bro? — KitKit, Dec 14 '17 at 09:37
