DDG seems to be requiring a referer header. I had success changing the cell that defines search_images to the following:

from fastcore.all import *
import time
import json

def search_images(term, max_images=200):
    url = 'https://duckduckgo.com/'
    res = urlread(url,data={'q':term})
    searchObj = re.search(r'vqd=([\d-]+)\&', res)
    requestUrl = url + 'i.js'
    params = dict(l='us-en', o='json', q=term, vqd=searchObj.group(1), f=',,,', p='1', v7exp='a')    
    headers = dict( referer='https://duckduckgo.com/' )
    urls,data = set(),{'next':1}
    while len(urls)<max_images and 'next' in data:
        res = urlread(requestUrl, data=params, headers=headers)
        data = json.loads(res) if res else {}
        urls.update(L(data['results']).itemgot('image'))
        requestUrl = url + data['next']
        time.sleep(0.2)
    return L(urls)[:max_images]
