Here's a simple script to download a complete set of test images.
It will create a directory directly below the script directory, named test_images
and load images there (if not already downloaded)
This location can be changed by modifying self.imagepath

import os
from pathlib import Path
import requests

class ImagePaths:
    def __init__(self):
        # Set directory anchor
        os.chdir(os.path.abspath(os.path.dirname(__file__)))
        self.homepath = Path('.')

        self.imagepath = self.homepath / 'test_images'
        self.imagepath.mkdir(exist_ok=True)
        self.image_url_list = {
