"Using JPEGs in this situation would be kinda pointless no? If you can somehow modify the hard -coded instruction sets in the browser or offline image viewers, wouldnt that be a virus itself??:) If you could do this, you could make the image viewer delete any pictures opened, etc." Thank you for proving my point. grin Seriously though, that's part of my point.. if you can do this, why not do something incredibly easier that will spread your virus much more, y'know? The good part out of all this (from my opinion) is that people are starting to doubt the oh-almighty authoritaw from McAfee and others, which may break a little bit of the Palpatine hold they've got on customers. =DarkPen=
