Traditional anti-spam is defenseless!!!!!

Recently I was going through a article somewhere I read that over the past several months, through processing billions of email messages, many email users identified an increase in this particular subset of spam, containing images only.
Traditional anti-spam technology -- such as content-based, Bayesian filtering, Heuristics and URL filtering -- is practically defenseless against this image-based spam, leaving organizations open to floods of these types of email.
I am a regular email user , I am using a antispam which works at the ESP technology , and uptill now I have not experienced any spams in my mail.This anti spam is know as spamjadoo.
