Just to clear up/finish up what Astroman was pointing out, and to add to what dragon said... When there are other people in a picture where they are in the background, or just in the picture, than it
is perfectly legal to post these pictures. To give an example of what is not legal is to post a picture of a person who is too young to conduct the activities they are engaging in (i.e. child pornography), or to post a picture of someone that is purposely trying to cast them in an inaccurate, and damaging light... As for the the aforementioned circumstances, there hasn't been anything that I have ever noticed that breaks those laws, if there is, I guarantee that I will remove them immediately. Thanks for the heads up and now back to the happy posting!!!
