The only "image" Spam that is currently getting through my filters is 
the "stock scam" images and they are different everytime I see it and 
they are using wavy text, odd colors and mixed fonts, etc... to try 
and fool the OCR scanners.

So, my question would be, how effective are the OCR scanners when the 
Spammers are doing this?

Since I put my new Spam Trap in place I have seen a reduction of this 
Spam getting through. It appears the honeypots are seeing the sources 
of the images first (or close to it) and stopping that source... 
ofcourse they rotate sources through out the day, but the honeypots 
are getting over 2000-3000 new IP address every day. The "hit rate" on 
the now blacklisted source is fairly high.


What spam trap did you put in place?
