        OR, unless the person that wrote the original source can just tailor
it to "run" the code once the graphic viewer (determined in advance) is
invoked to view the graphic. If someone wanted to, they could "embed" code in
their image file, and then customize it to the point where it interacts with
Graphic Workshop for example, will read the file, and then "load" the
executable code within the file. As long as the person isn't receiving it as 

graphic, they can be sure that they're going to be infected. Simple, but
difficult.
