You first need to load your image and convert it using base64.

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);

Then you add $base64 variable to session

session_start();
$_SESSION['product_number'.$base64 ] = true;
