Riddle solved. There was a change  on Nov 20, 2013:
Import PIL instead of just the Image class since it doesn’t resolve on all platforms.
-import os, imghdr, urllib, urllib2, sys, Image, argparse, zlib, unicodedata, re +import os, imghdr, urllib, urllib2, sys, PIL, argparse, zlib, unicodedata, re
Change PIL to Image in scraper.py  and resize works again.
