Understanding how Python sockets are used to send large number of bytes

I am trying to send an image via python sockets. I wrote a simple script for doing it.

server.py

import socket
import cv2
import sys

c = 0
q1 = '127.0.0.1'
q2 = 10001

s = socket.socket()
s.bind((q1, q2))
s.listen(5)

image_path = sys.argv[1]
with open(image_path, 'rb') as fh:
    print(fh)
    print(dir(fh))
    l = list(fh)
    print(len(l))
    c, addr = s.accept()
    if c != 0:
        for i in fh:
            c.send(i)

client.py

import socket
import cv2
import time

s = socket.socket()
q = '127.0.0.1'
p = 10001
condition = True
s.connect((q,p))
counter = 0

with open('recieved_image.jpg', 'wb') as fh:
    while condition:
        counter = counter+1
        img = s.recv(1024)
        
        if img == b'':
            condition = False
        fh.write(img)
        
print(counter)

Now this is the problem. In my case, when I run python server.py test.jpg, the length of list(fh) is 374. And those parts from list(fh) are sent one at a time via socket. But when I recieve them from client.py, the counter variable increments only one time. Isn't it supposed to increment until 374? Can someone clarify on the things that I have understood wrong?

What I have tried:

server.py

import socket
import cv2
import sys

c = 0
q1 = '127.0.0.1'
q2 = 10001

s = socket.socket()
s.bind((q1, q2))
s.listen(5)

image_path = sys.argv[1]
with open(image_path, 'rb') as fh:
    print(fh)
    print(dir(fh))
    l = list(fh)
    print(len(l))
    c, addr = s.accept()
    if c != 0:
        for i in fh:
            c.send(i)

client.py

import socket
import cv2
import time

s = socket.socket()
q = '127.0.0.1'
p = 10001
condition = True
s.connect((q,p))
counter = 0

with open('recieved_image.jpg', 'wb') as fh:
    while condition:
        counter = counter+1
        img = s.recv(1024)
        
        if img == b'':
            condition = False
        fh.write(img)
        
print(counter)
