python - 在 Python 中使用 Tkinter 在弹出窗口上打开图像

Question

问题是当我选择 Bonuses 按钮时，我可以打开 TopLevel PopUp 窗口，但图像不会在 TopLevel PopUp 窗口中打开。这是一个 python 代码，如果这篇文章没有意义，我深表歉意，因为我以前从未使用过 stackoverflow。

import tkinter as tk
from tkinter import ttk
from tkinter.messagebox import showinfo


def Impossible():
    win = tk.Toplevel()
    win.wm_title("Impossible")

    width, height = win.winfo_screenwidth(), win.winfo_screenheight()
    win.geometry('%dx%d+0+0' % (width, height))

    python_image = tk.PhotoImage(file=r"C:\Users\Ryan\PycharmProjects\pythonProject3\output-onlinepngtools.png")

    my_label = ttk.Label(win, image=python_image)
    my_label.grid(row=1, column=0)


def popup_showinfo():
    showinfo("Window", "Hello World!")


class WheresWaldoApp(ttk.Frame):

    def __init__(self, master):
        ttk.Frame.__init__(self, master)
        self.pack()

        self.button_bonus = ttk.Button(self, text="Bonuses", command=Impossible)
        self.button_bonus.pack()

        self.button_showinfo = ttk.Button(self, text="Show Info", command=popup_showinfo)
        self.button_showinfo.pack()


root = tk.Tk()
app = WheresWaldoApp(root)
root.mainloop()
