N.P.
I don't use instagram or whatever you're using but I pull photos off my camera and post them to my private facebook account. I have the settings set so that only my friends and family can see the photos so unless any of my friends or family are pervs and I don't know it, the pictures are ok. If any of my friends or family are pervs, I have bigger issues than whether they have a photo of her or not because they see her in person. This is why I don't have an issue with posting the photos to a private account. Would I post them to a public account that can get crawled by web spiders and have the photos harvested by search engines? Nope. Understand your privacy settings and share some snapshots!
