I have some url, for example :
var JackieChanFacebookPage = "https://www.facebook.com/jackie";
or
var JasonStathamFacebookPage = "https://www.facebook.com/JasonStatham";
or
var BillGatesLinkedInPage = "https://www.linkedin.com/in/williamhgates";
or
var JonSkeetGooglePlusPage = "https://plus.google.com/+JonSkeet/posts"
How can I extract profile photo from all of the above links
You can't extract the profile picture from a link. You need to use facebook apis, to manipulate facebook data.
