Calling Json script and displaying the Images within the script

I'm trying to access a Json script, it is in a domain. The script holds a couple of images, which are hyperlinked. I've tried using WWW to access the script, but the image i received was a picture of a huge red question mark. Clearly I'm going about the wrong way with this. So i'm assuming I'm supposed to decode the json script through unity and then display the image with the ability to see next/previous image by clicking? I'm unfamiliar with Json so how about would i call the script and read the the images it's calling?

This is what my code looks like, the code works since I've tried another non Json domain with just an image- and it works perfectly fine.

     void Start ()
 
     {   
         renderer.material.mainTexture = new Texture2D(4,4, TextureFormat.DXT1, false);
         url = "http://hosting.xivmedia.com/JsonHome/JSON/more_games.json";
        
             www = new WWW(url);
             StartCoroutine(WaitForSeconds(www));
     }
 
     IEnumerator WaitForSeconds(WWW www)
     {
         yield return www;
         www.LoadImageIntoTexture(renderer.material.mainTexture as Texture2D);
 
         if (www.error == null)
         {
             Debug.Log("WWW Ok!: " + www.data);
             imageLoaded = true;
 
         }
         else
         {
             Debug.Log("WWW Error: " + www.error);
         } 
     }
 
     void OnGUI()
     {
         GUI.DrawTexture(new Rect(20, 80, 100, 100),     renderer.material.mainTexture as Texture2D,  ScaleMode.StretchToFill);
  
     }
