Loading images from AssetBundle

I am able to extract and instantiate a prefab from the asset bundle using the code below. But I wish to extract some png sprites from the asset bundle. Also I need to follow a hierarchy because I am loading those sprites onto gameobjects at runtime. After much searching on the internet, I couldn’t find a solution. Any help? Thanks.

using System;
using UnityEngine;
using System.Collections;

public class CachingLoadExample : MonoBehaviour {
	public string BundleURL;
	public string AssetName;
	public int version;
	void Start() {
		StartCoroutine (DownloadAndCache());
	IEnumerator DownloadAndCache (){
		// Wait for the Caching system to be ready
		while (!Caching.ready)
			yield return null;
		// Load the AssetBundle file from Cache if it exists with the same version or download and store it in the cache
		using(WWW www = WWW.LoadFromCacheOrDownload (BundleURL, version)){
			yield return www;
			if (www.error != null)
				throw new Exception("WWW download had an error:" + www.error);

			AssetBundle bundle = www.assetBundle;

			if (AssetName == "")
			GameObject go = (GameObject)Instantiate(bundle.LoadAsset(AssetName));
			// Unload the AssetBundles compressed contents to conserve memory
		} // memory is freed from the web stream (www.Dispose() gets called implicitly)

Ok I managed to find it :

Sprite newSprite =  bundle.LoadAsset<Sprite>("assets/resources/images/snap.png");
