Raw Image File(s) Question

[twertsy]

I'm just curious about where the uploaded images go, and who may have access to those original files? The reason is that I was reviewing some of my photos and noticed that I have location services turned on in my phone for photos. This metadata follows an uploaded image. It can't be retrieved by the normal individual viewing posts but I'm fairly certain that if someone had access to the actual uploaded image it could be discovered. I'm sure some folks wouldn't like people knowing where pics were snapped in some cases.
