National Geographic

Q: Is it permissible to keep a National Geographic in my house when there is the possibility that it will have immodest pictures?
A: It is impossible to invalidate an entire book or magazine on account of one picture. What you should do is to color over the picture or put a sticker over it. After all, this is a rare occurrence. Destroying a picture on a wall in the street is a communal question, but you can do what you want if it is your own book or magazine.
