          FbDebug.Log("USerPicture called");
          WWW url = new WWW("http://i1.wp.com/a0.twimg.com/sticky/default_profile_images/default_profile_1_normal.png?resize=64%2C64");
  
  
          yield return url;
          //profilePic.renderer.material.mainTexture = textFb2;
  
          Debug.Log(url);
          url.LoadImageIntoTexture(userTexture);
          Debug.Log("Working");
      }
