In reply to Mike Lates:
It's unusual to get a photo voting thread that's complaining about the
lack of a voting option on a photo!
The guidelines on the moderation page for the People category are
Group photos and photos of people in a climbing or mountaineering environment or at least linked to a UKC meet. Photos of climbers in action where the climber expression is much more significant than the route they are climbing.
When I'm moderating, the rule of thumb I use is that if a picture is only going to be of interest to those who know the person in the photo then it probably belongs in the People category. So the first you've linked to feels more like landscape, the second probably People.
