You can NOT make a jpeg executable. Maybe on a unix system, by using chmod, but it still isn't executable. When you open a file (double click or whatnot) the OS determins what to do with that file, not the file itself. So when you double click a jpg, the os says, hey, its a jpg, show me the picture in MS Paint (or whatever program you use. Try it sometime. Take notepad.exe and rename it to notepad.jpg. What happens? You get an error saying that the jpg file is corrupted. It does NOT execute notepad. So the only way that this would be possible is if you installed a picture editor that was designed to run exactly what was in the jpg, not just show the jpg. As far as I know, there isn't any. The closest thing would be an animated gif, but that is still not executable.... Open an animated gif file in paint or photoshop, and it doesn't run. It just sits there.... You want animation, you have to open the file in a web browser or a program designed for viewing/editing animated gif files..
