Unstoppable picture spam.

Hello there!

Four times a day since the end of April, I have been blessed with 
e-mails containing text as pictures. I'm pretty sure they're from the 
same source. They all share the same "look": Text on a colored 
background (light red or light green). The contents of the text differs 
from time to time.

Have anybody received these e-mails? The spammer seems to be 
unstoppable. So any suggestions would be nice. It's the first time, I 
haven't been able to stop them within a few days.

Best regards,
Søren
