如何在Tkinter中跨窗口访问图像列表？

import tkinter as tk
from PIL import ImageTk, Image

class ImageListWindow(tk.Toplevel):
    def __init__(self, master, image_list):
        super().__init__(master)
        self.title("Image List Window")
        
        self.image_list = image_list
        
        self.canvas = tk.Canvas(self)
        self.canvas.pack()
        
        self.show_images()
    
    def show_images(self):
        for image_path in self.image_list:
            image = Image.open(image_path)
            image = image.resize((200, 200))  # 调整图像大小
            photo = ImageTk.PhotoImage(image)
            
            self.canvas.create_image(0, 0, anchor=tk.NW, image=photo)
            self.canvas.image = photo  # 保持对图像的引用，防止被垃圾回收

def open_image_list_window():
    image_list = ["image1.jpg", "image2.jpg", "image3.jpg"]  # 图像列表
    
    image_list_window = ImageListWindow(root, image_list)

root = tk.Tk()

button = tk.Button(root, text="Open Image List", command=open_image_list_window)
button.pack()

root.mainloop()
