python与tkinter结合写的简易相册预览(原创)
这两天一直在学习Tkinter,感觉其中的元件布局，有点复杂，不容易控制，因此，写了此例算作是练习一下了（其中用到了，Entry, Button, listbox, canvas,scrollbar等等），有高手发现不准确之处，希望指点一二：）python 代码

[*]
[*]
[*]if __name__ == '__main__':
[*] root = Tk()
[*] root.geometry('800x600+50+50')
[*] view = ViewPhotos(root)
[*] root.mainloop()
补充一点：from ImageTk import PhotoImage 这里的ImageTk 需要下载包(PIL)重新安装（http://www.pythonware.com）.
因为，Tkinter 中的PhotoImage()支持的图片格式比较少(gif,ppm,pgm),所以，如果需要处理其它格式的图片，就需要ImageTk哩. 它的PhotoImage()支持gif,jpeg,tiff,bmp等,处理常用的图片，够用了。。。 ^ _^
