Does anyone know what the legalities are if somebody posts pictures of my child on youtube without my consent?

I looked quickly online and couldn't find anything close you what you were interested in. My best suggestion would be to contact YouTube, tell them your underage child's images/videos have been uploaded to the site by (insert username), and ask them to have those images removed. You cannot sue YouTube, as it were, because they are just providing the space, not verifying the content. You can, however, talk with them personally about getting those taken down. If the person uploads the videos a second time, you could talk to YouTube about banning the person. Your third option is to contact the user directly and ask them politely to edit out your child from the content they have posted. Keep in mind that this will vary if it is a situation where your e-school child was inadvertantly caught in a video by an adult or if it was a high school teen videotaped by a friend. If your child is older I'd recommend talking to them first about the video, unless of course they don't want it up there either. If it's an enemy of the child, work with YouTube about banning the member, since the video/images a probably going to be more malicious then if it is a friend who has posted material. Hope that helps!
