Is the 'Madeleine McCann' photo a fraud?

Can the online community help cast light on the "Madeleine McCann" photo?

During the last Presidential election Dan Rather's CBS ran a story about George Bush's military record which was famously exposed as a fraud by bloggers. The ability of the internet to sweep up expertise from obscure corners brought typewriter analysts to the service of journalism and truth.

Surely there are people with enough expertise in enhancing digital photos, forensic examination of images and face matching who can help?

It will be an interesting test of the maturity of citizen journalism to see if online outlets or mainstream ones provide the next step forward in this story.
