Python Label image doesn't exist but os.path says it does

Question

Here is the code that is driving me crazy:

from tkinter import*
import os.path
class About:
    def __init__(self):
        font1='tahoma 12'
        win=Tk()
        print(os.path.isfile('logo.gif'))#It returns true
        Label(win,image="logo.gif").pack()                
About()

Answer 1

Label(win,image="logo.gif").pack()

The image parameter won't accept a filename. According to this tutorial, "the value should be a PhotoImage, BitmapImage, or a compatible object." It goes on to discuss the PhotoImage class, which you should use instead.

You can use the label to display PhotoImage and BitmapImage objects. When doing this, make sure you keep a reference to the image object, to prevent it from being garbage collected by Python's memory allocator. You can use a global variable or an instance attribute, or easier, just add an attribute to the widget instance:

photo = PhotoImage(file="icon.gif")
w = Label(parent, image=photo)
w.photo = photo
w.pack()
