Always sign your pictures. It gives you legal right to the picture as well. No one can fight with you, when you name is on it. I have had my pictures used on other sites. Then I started signing them, and would like to see someone try to use them. If its just a random pic, you don't care about. Like a picture of a gun you got or something like that. Then I would not worry about it. But anything cool or hunting pics or etc i would do it
