The only thing I CAN think of is perhaps the jpeg file having a carefully crafted string somewhere that causes a buffer overflow in the viewing program but that'd have to assume it was being viewed with a specific decoder, compiled a certain way. Certainly a long shot given the wide variety of viewing programs and jpeg decoding libraries available ... certainly embedding pure executable code wouldn't help because the viewing program would just ignore it. >I also thought that most IRC viruses were script viruses?
