Dear XXXXXXX,
You can get a protective order against her for stalking. However as in any protective order you have to show there is a reasonable chance of harm and injury to yourself or your property. With the recent stalking situations involving Craig's list, you may not have a problem with that.
On the other hand, while the pictures you post may not be suggestive, she may have grounds to sue for posting the picture without permission. It is a violation of the right to privacy of the minor,for whom she is entrusted to care for, and whose privacy she is charged with protecting. It is illegal to publish (emphasis on publish) a photo of a minor without the permission of the parent or legal guardian. When you post to the Internet, you are publishing (see copyright law). Because a parent or legal guardian may change their mind, then at the moment permission is no longer given, (she expresses that it can no longer be posted/published), and it remains, you can be sued.
Because of the high risk generally on the Internet of others, not necessarily you, seeing that picture and using it to identify a potential victim, you would most likely lose in court.
The argument that you also appear in the picture is not lost. So the question is moot if you are a parent of the child, else it holds true.
