推荐答案
我试图将图像应用于图像标签的text属性.这是固定代码.
I was attempting to apply the image to the text attribute of the label instaed of the image. Here is the fixed code.
url = self.threadLinkList[self.y]+'.gif'
imageName=self.threadLinkList[self.y][-11:-4]+'.gif'
print(imageName)
urllib.request.urlretrieve(self.threadLinkList[self.y],imageName)
imgfile = Image.open(imageName)
imgfile = imgfile.resize((150,150),Image.ANTIALIAS)
# img = Image.open(file)
print(imgfile)
self.threadImage = ImageTk.PhotoImage(imgfile)
self.threadLabelImage.config(***image*** = self.threadImage)
self.threadImage.image = imgfile
