试验动态加载图片，代码如下：

using UnityEngine;
using System.Collections;

public class DynamicLoad : MonoBehaviour
{
    Texture2D txt;

    IEnumerator Start()
    {
        string path = Application.dataPath + "/Title000.png";
        WWW www = new WWW("file://" + path);
        yield return www;
        
        txt = new Texture2D(200,200);
        txt = www.texture; // 方式一
        //www.LoadImageIntoTexture(txt); // 方式二

    }

    void OnGUI()
    {
        if (txt != null)
        {
            GUI.DrawTexture(new Rect(0, 0, 200, 200), txt);
        }
    }
}
