For the record, I got:

 >>> import urllib
 >>> SAT_URL = 
"http://adds.aviationweather.gov/data/satellite/latest_BWI_vis.jpg"
 >>> satpic = urllib.urlopen(SAT_URL, proxies=0 )
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "C:\Python26\lib\urllib.py", line 79, in urlopen
     opener = FancyURLopener(proxies=proxies)
   File "C:\Python26\lib\urllib.py", line 617, in __init__
     URLopener.__init__(self, *args, **kwargs)
   File "C:\Python26\lib\urllib.py", line 129, in __init__
     assert hasattr(proxies, 'has_key'), "proxies must be a mapping"
AssertionError: proxies must be a mapping

However, urllib.urlretrieve(...) works.
