help with sending and receiving pics taken

[mcgrim]

I continued to work on it, by turning bytes back into images, and I am now getting an error on the client side,
even though the files seem to be transferred.

Error:
Traceback (most recent call last):
  File "C:/Users/PycharmProjects/client-server/client.py", line 31, in <module>
    img = Image.open(io.BytesIO(data))
  File "C:\Users\\PycharmProjects\client-server\venv\lib\site-packages\PIL\Image.py", line 2818, in open
    raise IOError("cannot identify image file %r" % (filename if filename else fp))
OSError: cannot identify image file <_io.BytesIO object at 0x076EE450>

SERVER

import cv2
import time
import socket
import glob
import os

host = "127.0.0.1"
port = 5000

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((host, port))
s.listen(5)
print("server started...")

path1 = (r"C:\Users\Desktop\opencvpics")


def readFileImages():
    st = os.path.join(path1, "*.png")
    print(st)
    return glob.glob(st)


list1 = readFileImages()
print(list1, "list1......")
print(type(list1))

while True:
    c, addr = s.accept()
    print(f"connection from {addr} has been established !")
    c.send(bytes("welcome to the server".encode()))

    for pics in list1:
        f = open(pics, 'rb')
        l = f.read(1024000)
        while (l):
            c.send(l)
            print('Sent ', repr(l))
            l = f.read(1024)
        f.close()

        print('Done sending')
        c.send('Thank you for connecting'.encode())

CLIENT

import socket
import cv2

from PIL import Image
import io

import pickle


host =  "127.0.0.1"
port = 5000

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))

s.send('Hello server!'.encode())

with open('received_file.png', 'wb') as f:
    print('file is open')

    #while f:
    print('receiving data...')
    data = s.recv(1024)
    print('data=%s', data, "ASDFASDSADFASDFVSSDSAFSADDFDSAFD")
    f.write(data)
    print('Successfully get the files')

    print('connection closed')
    print(type(data))
    print(len(data))
    img = Image.open(io.BytesIO(data))
    img.show()

s.close()

P.S.
The directory in the client contains a few images, and I desire to send them all to the client.
