在tkinter中循环浏览图像

from tkinter import *
from PIL import ImageTk, Image

root = Tk()
root.title("Image Viewer")

def browse_images():
    global current_image_index
    current_image_index += 1
    if current_image_index >= len(image_list):
        current_image_index = 0
    image_path = image_list[current_image_index]
    image = Image.open(image_path)
    image = image.resize((400, 400))  # 调整图像大小
    photo = ImageTk.PhotoImage(image)
    image_label.configure(image=photo)
    image_label.image = photo  # 保持对图像的引用

image_list = ["image1.jpg", "image2.jpg", "image3.jpg"]  # 图像文件路径列表
current_image_index = 0  # 当前图像索引

image_label = Label(root)
image_label.pack()

browse_button = Button(root, text="Browse", command=browse_images)
browse_button.pack()

root.mainloop()
