Image spam is old news. The spammers use [WIKI]botnets[/WIKI] to send uniquely modified images in each spam email. The images have to be unique - otherwise spam filters could simply just drop known spam images.

So far, the images have typically been modified by adding colours, changing fonts and inserting random dots and lines.

Over the last few days, we're seeing more image spam that is rendering the spam text with a pseudo 3D layout.

Generating images like this is of course more computing intensive...but hey, spammers have lots of computing power at their disposal via the huge botnets they are running. It's not like they couldn't afford to render unique 3D spam for every recipient.
