I have a direct link like this: https://picjumbo.com/download/?d=cow.jpg&n=cow&id=1. But I cannot download it using urllib.request.urlretrieve() because when I access this url, the browser will download it automatically.
You can do the following:
>>> import requests
>>> content = requests.get('https://picjumbo.com/wp-content/themes/picjumbofree/run.php?download&d=cow.jpg&n=cow').content
>>> with open('downloaded_img.jpg', 'wb') as img:
... img.write(content)
...
