Here is a short script that goes to the lost password page, finds the captcha, and downloads the image to out.jpg.

This script requires the lxml library.

Hope this helps. Cheers!

import urllib2
import lxml.html

headers = {
    'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Gecko/2010010' \
    '1 Firefox/4.0.1',
    'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
    'Accept-Language':'en-us,en;q=0.5',
    'Accept-Charset':'ISO-8859-1,utf-8;q=0.7,*;q=0.7'}

req = urllib2.Request('http://www.amaderforum.com/login.php?do=lostpw', None,
                      headers)
f = urllib2.urlopen(req)
page = f.read()

tree = lxml.html.fromstring(page)
imgurl = "http://www.amaderforum.com/" + \
      tree.xpath(".//img[@id='imagereg']")[0].get('src')

req = urllib2.Request(imgurl, None, headers)
f = urllib2.urlopen(req)
img = f.read()

open('out.jpg', 'wb').write(img)
