Answer 1

You should use the GD library

Just create a new image with the width and height from the paramaters

https://www.php.net/manual/en/function.imagecreate.php

script.php?width=200&height=300

$width = (int)$_GET["width"];
$height = (int)$_GET["height"];
header("Content-Type: image/png");
$im = @imagecreate($width, $height) or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
imagepng($im);
imagedestroy($im);
