Pictures can help build trust for sure, but I can tell you that pictures do absolutely no good if I do not trust you to start with, If I do not know you they will help build trust though. I hope this is clear. But let me say if I think you are dishonest to start with i will not even believe pictures. But if I am just getting to know you pictures will help. Maybe that explains it better.
Perfectly clear. I know exactly what it means to deal with trustworthy people.
