(snipped)

Or, one can forego regular expressions:

prefix = '.thumbnail'
for p in os.listdir(dir):
    root, ext = os.path.splitext(p)
    if not os.path.isfile(os.path.join(dir, p)) \
    or ext.lower() not in ('.jpg', '.jpeg') \
    or root[-10:].lower() == prefix:
        continue
    if os.path.isfile(os.path.join(dir, "%s%s%s"  % (root, prefix,
ext))):
        print "A thumbnail of %s already exists" % p
    else:
        print "Making a thumbnail of %s" % os.path.join(dir, "%s%s%s"
%
        (root, prefix, ext))
