A pic holding a card with contact info can easily be edited/photoshopped to show whatever anyone wants. With knowledge of photoshop I can erase decades off a person's actual age and can easily shed them 50+ pounds. It's still the same image of that person, but not what they look like in reality.
Personally, I'm skeptical when I see the professional photos and think it's best to rely on what the community's experiences have been and just beware of the shill.
