This digitally altered picture has been featured widely on blogs debating the existence of ancient giants—speculation fueled in part by false reports of huge skeletons unearthed in India, Saudi Arabia, and elsewhere.

The image, created by “Amaranto,” appears to be a less than serious attempt at a hoax—note the huge revolver in the skeleton's hand.

Avi Muchnick runs Worth1000, the Web site that sponsored the photo-manipulation contests that inspired the fake photos in this gallery.

“We have thousands of people who regularly create images like these in image-editing tools like Phoenix and Photoshop," Muchnick said. "So it's no surprise to us when some of these images get passed around the Web as authentic depictions of actual events."
