bkok - New PHP function to revolutionize language ---- important

Hello I see that in php does not have a function that sets url src and href so that would be a result of this? It is for cases like these <Img src = "../../ images / securance / abc.jpg"> as we see it is showing all the way to be able to display the imagewith a function I nomei of "bkok & BKO" this script would asim <Img src = "securit.php? Id = 21 =" /> as we see not pasamos the image path but a php page that will redirect to the image if called via href or src example bkok ('src', 'href'){ if (isset ($ _GET ['id'] == "21")){ header ("Location: ../../imagens/securance/abc.jpg"); } } BKO{ echo 'this page does not exist'; } What do I tell if it was the User try aCesar the site via url it will not be redirected more if it is called via src or href he will be redericionado that if we can do will change the very systems and security not espondo the directories of the site hugs agurado return Este e-mail foi enviado por um computador sem vírus e protegido pelo Avast. www.avast.com
