Getting help about why does this code doesn't shows any image.

main.py

from PIL import Image, ImageTk
from io import BytesIO

import tkinter as tk
from collections import namedtuple
import sys

creative_common_image_url = 'https://api.creativecommons.engineering/v1/images'

    'license_type': None,
    'categories': 'illustration',
    'extension': None,
    'aspect_ratio': None,
    'size': None,
    'source': None,
    'searchBy': None
}

ImageResult = namedtuple('ImageResult', 'preview url')

def request_image(url):
    response = requests.get(url)
    img_data = BytesIO(response.contet)
    return Image.open(img_data)


def parse_results(result):
    for r in result:
        preview_url = r['thumbnail']
        url = r['url']
        if not any(map(lambda s: s.endswith('svg'), [preview_url, url])):
            try:
                preview = request_image(preview_url)
                yield ImageResult(preview, url)
            except:
                ...


def images(key_word):
    params = default_params.copy()
    params.update(q=key_word)
    print(f'{key_word=}, {params=}')
    response = requests.get(creative_common_image_url, params=params)
    result = response.json()['results']
    return list(parse_results(result))


root = tk.Tk()
for i in images('horse'):
    # i is a pillow Image that had created with Image.open()
    image = ImageTk.photoImage(i.preview)
    label = tk.Label(root, image=image)
    label.image = image
    label.pack(side='left', fill='both', expand='yes')
    break # braeking here so I test just test the first one.

root.mainloop()
sys.exit(0)
