There appears to be an odd networking issue with how urllib2 sends HTTP requests. Downloading an image from maw.liquifire.com gives an error:

$ python -c 'import urllib2 ; urllib2.urlopen("http://maw.liquifire.com/maw?set=image[2302.000.13314 a]&call=url[file:325x445]")'
Traceback (most recent call last):
  File "<string>", line 1, in <module>

    return _opener.open(url, data, timeout)

    response = self._open(req, data)

    data = self._sock.recv(self._rbufsize)

Downloading the same image using wget works fine:

$ wget 'http://maw.liquifire.com/maw?set=image[2302.000.13314 a]&call=url[file:325x445]'
