Tkinter image not showing or giving an error
提问by Arktri
I have tried two different things to try to get an image to show in a label
我尝试了两种不同的方法来尝试将图像显示在标签中
#This gives " TclError: couldn't recognize data in image file "TestImage.gif" "
imgPath = "TestImage.gif"
photo = PhotoImage(file = imgPath)
label = Label(image = photo)
label.image = photo # keep a reference!
label.grid(row = 3, column = 1, padx = 5, pady = 5)
and
和
#This gives no error but the image doesn't show
imgPath = "TestImage.gif"
photo = PhotoImage(imgPath)
label = Label(image = photo)
label.image = photo # keep a reference!
label.grid(row = 3, column = 1, padx = 5, pady = 5)
The image is in the same folder as all the code. Any suggestions on how to show an image?
该图像与所有代码位于同一文件夹中。关于如何显示图像的任何建议？

Bryan Oakley is correct, the image is not a jpg in terms of its content, even though your filesystem thinks it's a gif.
Bryan Oakley 是正确的，就其内容而言，图像不是 jpg，即使您的文件系统认为它是 gif。
On my end I tried opening a jpg with your program and got the same error 'TclError: couldn't recognize data in image file "hello.jpg".'
最后，我尝试用你的程序打开一个 jpg 并得到同样的错误“TclError：无法识别图像文件“hello.jpg”中的数据。
So you can do this: Open your image with mspaint, then go to File > Save As and from the "Save As Type" dropdown, choose GIF. Then the code should work. This is what I used:
所以你可以这样做：用mspaint打开你的图像，然后去文件>另存为，从“另存为类型”下拉菜单中，选择GIF。然后代码应该可以工作。这是我使用的：
from Tkinter import *
root = Tk()
imgPath = r"hello.gif"
photo = PhotoImage(file = imgPath)
label = Label(image = photo)
label.image = photo # keep a reference!
label.grid(row = 3, column = 1, padx = 5, pady = 5)
root.mainloop()
(btw, if I changed line 7 above to photo = PhotoImage(imgPath)then like you, no image appears. So leave it as photo = PhotoImage(file = imgPath))
（顺便说一句，如果我将上面的第 7 行更改为photo = PhotoImage(imgPath)像您一样，则不会出现图像。所以将其保留为photo = PhotoImage(file = imgPath)）
