如何检索缩略图并将其显示为QListwidget项目？

我想直接从http://i.ytimg.com/直接阅读缩略图，而不使用谷歌gdata服务。谁能帮我？如何检索缩略图并将其显示为QListwidget项目？

`enter code here` 

#!/usr/bin/env python 
#_*_ encoding: UTF-8 _*_ 

from PyQt4.QtGui import QImageReader 

from PyQt4.QtNetwork import (QNetworkRequest, QNetworkReply, QNetworkAccessManager) 

from PyQt4.QtCore import QUrl 


def getThumbnails(self,numTitles): 

    thumbs = [] 
    thumbs[:]= [] 

    nam = QNetworkAccessManager() 

    for i in xrange(numTitles): 
     url = QUrl("http://i.ytimg.com/vi/" + self.tubeLinks[i] + "/default.jpg") 
     request = QNetworkRequest(url) 
     reply = nam.get(request) 
     image_reader = QImageReader(reply) 
     thumbs.append(image_reader.read()) 

    return thumbs

我delimmas是：

1.-如何测试拇指是否被成功读取？

2.-如何将它们添加到QListWidget项目使用pixmap？
