`$file` source image file add border to	`getimagesize` returns image size from given path
`imagecreatefrompng` creates GD image object from given PNG image	`imagesetthickness` set line thickness (border width, set to `15` pixels in our case)
`imageColorAllocate` creates color object to later use in image	`imagerectangle` creates rectangle
`/tmp/image.png` path to write generated image to

Usage example

<?php

$file = '/var/www/examples/heroine.png';
$size = getimagesize($file);
$im = imagecreatefrompng($file);

imagesetthickness($im, 15);
$c_green = imageColorAllocate($im, 46,204,64);
