Have been answered few threads ago and more... May be you didn't scan enough ^^

You can use FuzzyOCR module (But dont ask me how to use, I've never tried ^^)

Objet : Stock spam in images

I'm a newbie to the list and have been scanning recent posts to see if what I'm about to ask
 about has been covered but I haven't seen anything yet.

Lately I have been getting more and more of the stock alert spam but now all the good info i
s in an image and typically following the image is random text to fool the Bayesian filter. 
I think the random text thing has been covered here recently. It's frustrating when sa is gi
ving a
-1.6 (or so) score to these emails right off the bat. Quite a few of these aren't even getti
ng spam headers because they aren't scoring high enough. Is there some magical trick to help
 score these messages higher?
Maybe a future version of sa will incorporate an OCR module? :)
