Answer 1

Starting with this small image small.jpg

and this large image large.png

Running this:

#!/usr/local/bin/php -f
<?php
   list($width, $height) = getimagesize('small.jpg');
   $src  = imagecreatefromjpeg('small.jpg');
   $dest = imagecreatefrompng('large.png');

   // Copy 
   imagecopy($dest, $src, 300, 20, 0, 0, $width, $height);

   // Write result 
   imagepng($dest,"result.jpg");
?>

gives this
