Someone brought up Photoshop, in regards to the Air Farce One scare. So I thought I'd show you guys an example of how it can be used, and how you can tell if a photo is an original or has been tampered with, and who's digital signature is on the altered copy, when it is saved.
Digital signatures are fairly easy to follow, be careful where you leave them!

For those you not that computer-savvy, Photoshop is image-editing software (the most popular). You can virtually superimpose one image onto another etc. Photoshop is often used to put heads on other peoples' bodies (as in the case of some Glam magazines) etc. Even an amateur with this software can make convincing, yet fake photos.
A quick-and-dirty way to find out if an image has been altered in any way, is to open that image in a Hex (or even simple text) editor.
Note: For those of you not so computer-savvy - images when opened in text editors (like Notepad) show the Hexidecimal code for the image. Computers only understand numbers, so it uses Hexidecimal to represent pairs of Binary numbers. Binary numbers are 1's and 0's. A pattern of these numbers together, represent the image to the computer, which converts it to what you see. Hexidecimal is a way of shortening up Binary sequences.
When an altered (or newly created) image is saved in Photoshop, it (Photoshop) will record basic details about the image depending on how the image-saving preferences are set. You can record additional text into the image, such as copyright information, or even a comment. And no, Ducky did not save any copyright information for the images.
Below are the images - shown normally and opened in a Hex editor. You will see 'Ducky' in each one:
