One type of spam not caught, nor "trainable"

Spam Sieve is working great on 99% of my spam, but a few weeks ago I started getting spam from my own e-mail address (spoofed) for with “Card Test” as sender and “Card Test” as recipient. They are for Microsoft/Viagra, and they load an image one I click on it to select and train as spam.

Anyways, not a major deal, but certainly an annoyance as I am getting about 50 of these a day. Not sure why the training doesn’t seem to catch these.

Any help would be appreciated. I’m on latest mac OS and newest Spam Sieve.

Please see this thread.
