I saw this picture in this thread yesterday and on another site as well, so it must be making the rounds.
I was able to do some Google searches and I was able to find the original photographer who produced the image. I will include a link to his site below if anyone wants to check it out.
Thank you. I don't think any of us would like our photos used without proper credit. Also if we do use someone's photo we should link to their website so they get the traffic. Many people monetize their sites so more traffic means more money for them.
