Many of us would be of the opinion that you firewall would protect you from the ugly world. But this might not be the case. Even though your firewall works fine when you have logged in, it might not work when you have logged off.

Here is script to download images, from a website. I have taken the example of zune.net to download the images to my local disk.

you can alter it as you please:

import sgmllib
import re

class MyParser(sgmllib.SGMLParser):
A simple parser class.

def parse(self, s):
Parse the given string s.
self.feed(s)
self.close()

def __init__(self, verbose=0):
Initialise an object, passing verbose to the superclass.

sgmllib.SGMLParser.__init__(self, verbose)
self.hyperlinks = []

def start_a(self, attributes):
Process a hyperlink and its attributes.

for name, value in attributes:
if name == href:
self.hyperlinks.append(value)

def get_hyperlinks(self):
Return the list of hyperlinks.

return self.hyperlinks

import urllib, sgmllib

# Get something to work with.
f = urllib.urlopen(http://www.zune.net/en-us/mp3players/backgrounds/default.htm)
s = f.read()

# Try and process the page.
# The class should have been defined first, remember.
myparser = MyParser()
myparser.parse(s)

# Get the hyperlinks.
#print myparser.get_hyperlinks()
hlist = myparser.get_hyperlinks()
for links in hlist:
var_extn = links[-3:]
if(var_extn == jpg):
finalURL = http://www.zune.net+links
print finalURL
start = finalURL.find(480×640_)
end = finalURL.find(.jpg)
finalName = finalURL[start:end]
image = urllib.URLopener()
image.retrieve(finalURL,finalName+.jpg)
