Cannot download the image dataset
Hi, mtli, 

Thanks for your wonderful work. 

I'm trying to download your dataset using the get-images.py script. However,  I got the following issue, 

`File "get_images.py", line 27, in <module>
    urllib.request.urlretrieve(row[URL_COL], os.path.join(out_dir, name))
  File "/home/deng/anaconda3/lib/python3.7/urllib/request.py", line 247, in urlretrieve
    with contextlib.closing(urlopen(url, data)) as fp:
  File "/home/deng/anaconda3/lib/python3.7/urllib/request.py", line 222, in urlopen
    return opener.open(url, data, timeout)
  File "/home/deng/anaconda3/lib/python3.7/urllib/request.py", line 531, in open
    response = meth(req, response)
  File "/home/deng/anaconda3/lib/python3.7/urllib/request.py", line 641, in http_response
    'http', request, response, code, msg, hdrs)
  File "/home/deng/anaconda3/lib/python3.7/urllib/request.py", line 569, in error
    return self._call_chain(*args)
  File "/home/deng/anaconda3/lib/python3.7/urllib/request.py", line 503, in _call_chain
    result = func(*args)
  File "/home/deng/anaconda3/lib/python3.7/urllib/request.py", line 649, in http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden`

It seems that the service is down or my IP address is blocked. But I was also trying to use VPN, which has failed, either. 

Could you kindly help me out.
