Question about GDlib, and "Stacking" images

[JREAM]

This is my first time using GDlib, so I do this an it works well right.
I am doing two imagecopies() -- is that ok?

I want to stack images in order to make a character creator, so Ill have like 5 body parts stacked on top of eachother to create an image. Im not worried about positioning right now.

Is this the best way to go about it?
Would I just repeat this 5 times to get 5 png's layered and then on one image?

Thanks for time, If i fall asleep ill repsond once i wake up, been coding all night :P

<?php


$stamp = imagecreatefrompng('logo.png');
$stamp2 = imagecreatefrompng('pig.png');
$im = imagecreatefromjpeg('dog.jpeg');



$sx = imagesx($stamp); // Image Height
$sy = imagesy($stamp); // image Width

$sx2 = imagesx($stamp2); // Image Height
$sy2 = imagesy($stamp2); // image Width

// Copy the stamp image onto our photo using the margin offsets and the photo 
// width to calculate positioning of the stamp. 
imagecopy(
    $im, 
    $stamp, 
        imagesx($im) - $sx - 10, 
        imagesy($im) - $sy - 10, 
        0, 0, 
        imagesx($stamp), 
        imagesy($stamp)
        );
imagecopy(
    $im, 
    $stamp2, 
        imagesx($im) - $sx2 - 24, 
        imagesy($im) - $sy2 - 22, 
        0, 0, 
        imagesx($stamp2), 
        imagesy($stamp2)
);
// Output and free memory
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>

I've done very little work with gd, but assuming each layer has a transparent background, I think it should work. Although, you might need to tell gd to respect transparency.

Okay sweet.

I found a better way to do it from some guys example incase anyone wanted to know:

<?php
$layers = array();
$layers[] = imagecreatefromjpeg("maps/{$radar_id}_Topo_Short.jpg");
$layers[] = imagecreatefromgif("maps/{$radar_id}_N0R_0.gif");
$layers[] = imagecreatefromgif("maps/{$radar_id}_County_Short.gif");
$layers[] = imagecreatefromgif("maps/{$radar_id}_Highway_Short.gif");
$layers[] = imagecreatefromgif("maps/{$radar_id}_Rivers_Short.gif");
$layers[] = imagecreatefromgif("maps/{$radar_id}_City_Short.gif");
$layers[] = imagecreatefromgif("maps/{$radar_id}_N0R_Legend_0.gif");
$layers[] = imagecreatefromgif("maps/{$radar_id}_Warnings_0.gif");

$image = imagecreatetruecolor(600, 550);



for ($i = 0; $i < count($layers); $i++)
{
    imagecopy($image, $layers[$i], 0, 0, 0, 0, 600, 550);
}


header('Content-type: image/jpeg');
imagejpeg($image);
