Dirt bike

dirt bike, known as Dirt Bike in Windows Live Messenger, is a user account/display picture included in Windows XP and Windows Live Messenger. It depicts a dirt biker jumping in the air.

While it is known to have come from Corbis per the photo credits of ''Motorcycles! Step Into Reading - Level 3'' (which features the image on its cover), it is unknown who took it nor where it was taken; it is credited to "Royalty-Free/CORBIS" in said book due to Corbis not being public about royalty free photographer credits at the time. It does not specify its original title, which has also not been found due to it being taken down from stock photo sites before TinEye started indexing them. It has not been found on Photononstop either, which still hosts old Corbis photos to this day.
