I just looked at the photo, certainly not best practices (the fisherman's index finger sits directly on top of the gill plate with his middle finger along its outside edge so I don't see how you can say no fingers were even close. Further, it is pretty hard to successfully tail a fish, gain control, lift it a minimum of 4' out of the water, pass it to another person, pose for a photo, then properly lower back into the water in a few seconds. Suppose the definition of few seconds varies considerably though...).
All that being said, I believe that care was taken in handling the fish and it probably swam away quite strong. A guiding service is just that, a service and have certain expectations placed upon them. Those include pictures of your catch. We can debate it all day. Everyone has a different line but for the most part everyone wants to see stocks rebound and opportunities expand.
