Python based photobucket downloader

This is just a script I made in python that will download every image in a public photobucket gallery. 

from sgmllib import SGMLParser
import urllib, re, os
dirs = []
pages = []
check = True
total = 0
count = 0
length = 40
def mkdir():
    global DLlocation
    DLlocation = raw_input('Enter download folder:\n')
    if DLlocation:
        root,  tail = os.path.splitdrive(DLlocation)
        os.chdir(root+os.sep)

usage:
just need to enter a directory for the images and a link to a photobucket gallery.
