save image from link.

[Larz60+]

I got a not found from the url you supplied.
I would use requests module to fetch image, something like:
(using different image)

import requests
from io import open as iopen

def fetch_image(img_ur, save_filename):
    img = requests.get(img_ur)
    if img.status_code == 200:
        with iopen(save_filename, 'wb') as f:
            f.write(img.content)
    else:
        print('Received error: {}'.format(img.status_code))

testlink = 'https://vignette.wikia.nocookie.net/pdsh/images/9/95/Prettygoldilocks.jpg'

filename = 'Goldilocks.jpg'
fetch_image(testlink, filename)
