When we post photos here, we give up any copyright protection, per this site's Terms of Service/Use, so nobody owes you anything!
If I were to post a photo from this site on another website, newspaper, magazine etc., in theory I should get the permission of the copyright holder [AF or SK], and pay them a fee.
This is very standard old-fashioned copyright law, which pre-dates the Internet by centuries.
