这是显示来自URL的图像的代码:
def display_image(image_url):
# create image
image = Image.open(StringIO(urllib2.urlopen(image_url).read()))
image = ImageTk.PhotoImage(image)
# create display
root = tk.Tk()
root.title('captcha')
root.geometry("%dx%d+%d+%d" % (image.width(), image.height(), 0, 0))
# draw image
panel1 = tk.Label(root, image=image)
panel1.pack(side='top', fill='both', expand='yes')
panel1.image = image
# run display
root.mainloop()
I get the following output on my console:
Traceback (most recent call last):
File "vote.py", line 119, in <module>

File "vote.py", line 89, in display_image

我做错了什么?非常感谢您提供帮助。
