Left/Right quite obviously depends upon your point of view. The one you see to your left when looking at the picture is of course the one actually on the right the way they are standing. I interpreted Amarillo Mike's post to mean the one I saw to my left. A simple look at the guns shows this was the way he meant it as quite obviously the gent in the tan cap has the Smith while the one in red cap has the Fox. As I don't know either man I can only go by the gun they are holding.
This is Sorta like driving down the road & meeting an oncoming car. Assuming we are in the US, not England, & it is on the proper side of the road the car will be to your left, but IT is on the Right side of the road. You are each just looking in opposite directions.
