Loading an image from www, can i save it in playerprefs ?

If not then can i save it locally by any means ?

 

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.IO;
4.  
5. public class Test : MonoBehaviour {
6.     public IEnumerator Start () {
7.         WWW loader = new WWW("http://unity3d.com/sites/default/files/frontpage/learn.jpg");
8.         yield return loader;
9.         string path = string.Format("{0}/image.png", Application.persistentDataPath);
10.         Debug.Log(path);
11.         File.WriteAllBytes(path, loader.texture.EncodeToPNG());
12.     }
13. }

 

You can only save strings in the player prefs. That means you have to convert the byte array to a string before you can save. As you load, you do the other way. Auntie google knows how to do both of them.
Take care because there is a size limit:
