使用python构建可以发送信息，文件，图片，并且附带GUI界面的聊天系统

好的，实现这个聊天系统需要用到以下 Python 库：

1. tkinter：Python 标准 GUI 库，可以创建和管理 GUI 应用程序的各种组件，包括窗口、按钮、文本框、标签等等。

2. socket：Python 标准库之一，可以用于创建网络套接字，实现网络通信。

3. pickle：Python 标准库之一，可以实现对象的序列化和反序列化，用于在网络传输中发送复杂数据类型。

4. Pillow：Python 图像处理库，可以操作图像文件，包括打开、保存、缩放、裁剪、旋转等等。

5. threading：Python 标准库之一，可以创建多线程程序，实现并发执行。

下面是一个简单的可以发送文字、文件和图片，带有 GUI 界面的聊天系统的示例代码：

import tkinter as tk
import socket
import threading
import pickle
from PIL import Image, ImageTk
import os

class ChatClient:
    def __init__(self, host, port):
        self.host = host
        self.port = port
        self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.socket.connect((self.host, self.port))
        self.receive_thread = threading.Thread(target=self.receive)
        self.receive_thread.start()

    def receive(self):
        while True:
            try:
                data = self.socket.recv(1024)
                if data:
                    message = pickle.loads(data)
                    if isinstance(message, str):
                        self.receive_message(message)
                    elif isinstance(message, bytes):
                        self.receive_file(message)
                    elif isinstance(message, dict):
                        self.receive_image(message)
            except Exception as e:
                print(e)
                break

    def send(self, message):
        try:

    def receive_message(self, message):
        self.message_box.config(state=tk.NORMAL)

    def receive_file(self, data):

        self.receive_message('Received file: ' + filename)

    def receive_image(self, data):
        filename, imagedata = data['filename'], data['imagedata']
        with open(filename, 'wb') as f:
            f.write(imagedata)
        image = Image.open(filename).resize((200, 200))
        photo = ImageTk.PhotoImage(image)
        self.image_box.image = photo
        self.image_box.config(image=photo)

    def send_message(self, event=None):
        message = self.message_input.get()
        self.message_input.delete(0, tk.END)
        if message:
            self.send(message)

    def send_file(self):
        file_path = tk.filedialog.askopenfilename()
        if file_path:
            with open(file_path, 'rb') as f:
                filedata = f.read().decode('utf-8')
            filename = os.path.basename(file_path)
            self.send(filename + '|' + filedata)
            self.receive_message('Sent file: ' + filename)

    def send_image(self):
        file_path = tk.filedialog.askopenfilename()
        if file_path:
            with open(file_path, 'rb') as f:
                imagedata = f.read()
            filename = os.path.basename(file_path)
            self.send({'filename': filename, 'imagedata': imagedata})
            self.receive_message('Sent image: ' + filename)

    def run(self):
        self.window = tk.Tk()
        self.window.title('Chat Client')

        self.message_box = tk.Text(self.window, state=tk.DISABLED)
        self.message_box.pack(side=tk.TOP, padx=10, pady=10)

        self.scrollbar = tk.Scrollbar(self.window)

    client.run()
