The story surrounding Smile.jpg has been warped, the original picture is not of a dog, nor is it of any animal or person. It is of a creature unknown to us. The red picture and the picture in the photo that comes with the fake story are pictures constructed to go along with the altered version of the legend. The real Smile.jpg has long been lost along with the people who’ve seen it. How I know of this is because I have communicated with people that have known of instances of the email containing the picture long before it became an internet phenomenon. It is not smiledog.jpg, it is simply smile.jpg, and I doubt that the internet will ever uncover the original image as it is said to disappear by itself. If you ever get an email entitled Smile.jpg, DO NOT OPEN IT, delete it immediately. I believe that the image is of Satan itself.
