Who's this cowboy?

[jdcnow]

Is the cowboy in the ImageCrack pictures the same as the fine man in the Bryan Ockert pic? If they are the same man, Who is he? If they are different, then who are they?

ImageCrack - Cowboy 1 ImageCrack - Same cowboy, different pose

Bryan Ockert's site - Gallery 8, Pic Number 8

Thanks very much in advance for any helpful information.
