You can't. Unless it's getting popular then maybe you will see it coincidentally somewhere, but no you cannot find out.

Just do a Google "search by images" using your pics that you uploaded on your profile, it'll lead you to its source.

facebook is on the internet. The way you phrased that question is so wrong. But if you want to know if a picture you might expect to be posted by someone somewhere without your knowledge but you want to be really sure, you can use reverse image search on that picture. Try http://www.tineye.com/

Use Google Images On The Google Images Page to The Right On the Search Box you will See a Camera Button Click on it than Select the Photo From your Computer than Click Search and it Will Tell you Which Sites Has the Picture on it
