Código Python:

import urllib
import os
from BeautifulSoup import BeautifulSoup
 
url = raw_input('URL -> ')
 
f = urllib.urlopen(url)
data = f.read()
f.close()
 
soup = BeautifulSoup(data)
for counter, img in enumerate(soup.findAll('img')):
    if img['src'].startswith("http://"):
        ipath = img['src']
    else:
        ipath = url + img['src']
 
    try:
        local = open(img['src'].split("/")[-1]), "wb")
        internet = urllib.urlopen(ipath)
    except IOError:
        continue
 
    data = internet.read()
    local.write(data)
 
    internet.close()
    local.close()
 

Mas o menos quedaría así.
