Не работает кнопка tkinter и не подставляет изображение

Вот код. Нужна игра которая будет вычислять две одинаковые картинки, по типу игры pexeso

from tkinter import *
import random
from tkinter import messagebox
from PIL import ImageTk, Image

win = Tk()
win.geometry("460x450")

imgmain = ImageTk.PhotoImage(Image.open("IMG_6080.jpg").resize((200,200)))

rugby = ImageTk.PhotoImage(Image.open("IMG_6087.webp.png").resize((200,200)))

voleyball = ImageTk.PhotoImage(Image.open("IMG_6084.webp.png").resize((200,200)))
