Send an image through socket as binary data

I have a multithreaded echo server:

from socket import *
import threading
import thread

def handler(clientsock,addr):
    while 1:
        data = clientsock.recv(BUFSIZ)
        if not data:
            break
        msg = 'echoed:... ' + data
        clientsock.send(msg)
     clientsock.close()

if __name__=='__main__':
    HOST = 'localhost'
    PORT = 21567
    BUFSIZ = 1024
    ADDR = (HOST, PORT)
    serversock = socket(AF_INET, SOCK_STREAM)
    serversock.bind(ADDR)
    serversock.listen(2)

    while 1:
        print 'waiting for connection...'
        clientsock, addr = serversock.accept()
        print '...connected from:', addr
        thread.start_new_thread(handler, (clientsock, addr))

I would like to convert the server in order to return an binary image instead of the original message and modify the client accordingly.

Can someone point me an example?

If you have the image data in a string, you can just replace your call to clientsock.send(msg) with clientsock.sendall(image_data). You can just read the image data out of a file using something along the lines of:

image = open('my_image.jpg', 'rb')
image_data = image.read()
image.close()
