Dirt bike

dirt bike, known as Dirt Bike in Windows Live Messenger, is a user account 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.
