Python Get the URL of all posts of an Instagram user

I have written a small piece of code to download images from Instagram. Here is the code:

from bs4 import BeautifulSoup as soup
from urllib.request import urlopen as req
import urllib.request as reqq
from selenium import webdriver
import os


browser = webdriver.Chrome("D:\\Python_Files\\Programs\\chromedriver.exe")

url = "https://www.instagram.com/p/CFRY7X2AnOx/"

browser.get(url)
image_url = browser.find_element_by_class_name('KL4Bh').find_element_by_tag_name('img').get_attribute('src')

reqq.urlretrieve(image_url,"D:\\instaimg.jpg")

This works fine. But this can only download one image. Is there any way to get the URL of all the posts of a user so that all images posted by the user can be downloaded? Any help would be appreciated. Thanks!
