        This was assuming that this was with an image viewer. What if your
browser triggered a plugin like Adobe AcroRead, or Pkunzip, or some other app
to which the virus was triggered to execute? I can imagine that this is going
to be pretty common if someone acomplishes it. You would only have to fake a
PkSfx header to trigger Pkunzip to "run" the file, and bam! you could be
infected.
        Just a thought...
