i think that parents should have the right, of course, a well regularised one.
i do think it's an almost good idea if the parent knows how much exposure it is and thinks a bit before uploading. for example, where and how they share. /is shot. too sleepy to properly make a solid thesis.

a government forbidding parents to post their childrens' pictures is like another big brother.

i think it's a good idea if the picture is psot on facebook under an 'only friends' tag.
