Well you have two options you could use an ip system or a login system.
ip will something in the lines of :
<?php
$ip=$_SERVER['REMOTE_ADDR'];
//then add to db ip and the link of the image in a table where the combination is unique.
?>
login system
<?php
$id=$_SESSION['id'];
//then add to db id and the link of the image in a table where the combination is unique.
?>
The second option is better because the ip address is stored in the header and can be faked.
So you basically you will be some sql knowledge first.
