Scraping images in nested divs

I am trying to scrape the images from a personal imgur gallery: https://imgur.com/a/FIR1BL1 so I can then format them and prepare them for linking to my website. I want a list of all the image links, but for some reason I can’t get any. I also tried with a CSS selector but no luck. I suspect it might be because they are too deeply nested. Also I don’t have much experience with scraping.

This is what I came up with using Python and BeautifulSoup:

import requests
from bs4 import BeautifulSoup

# Make a GET request to the website
r = requests.get("https://imgur.com/a/FIR1BL1")

# Parse the HTML content
soup = BeautifulSoup(r.content, 'html.parser')

# Find the element with tag "div" and class "PostContent-imageWrapper-rounded"
div = soup.find_all("div", class_="PostContent-imageWrapper-rounded")

if div:
    # Find all the "img" elements inside the div
    img_tags = div.find_all('img')

    # Print the src attribute of each img element
    for img in img_tags:
        print(img['src'])
else:
    print("Div not found")
