Looks like it worked after all! And if not, I don't see why bayesian filters don't consider image tags as well. Sure, you might not be able to decipher the text on-the-run; but you know there's an image there, and the size of the image. If it's just a little clipart or icon, it could pass. You could then program your filter to look down on messages that start off with a large image, for example.

Get a better Bayesian filter. Words that are not in your corpus as either good or bad will not be used by the Bayesian filter to judge the message one way or another. This is not really true.

They just add a load of garbage text and it beats any spamfilter. I got many, MANY prescription-meds spam last year using this technique.
