Libit:
I was working on the same thing. The following is a solution -- but,
simple and best are relative.
This was taken from "PHP Graphics Handbook" by Kent et al.
<?
$original=imagecreatefromjpeg("apollo.jpg");
$watermark=imagecreatefrompng("xssportstransparent.png");
$osx=imagesx($original);
$osy=imagesy($original);
$wsx=imagesx($watermark);
$wsy=imagesy($watermark);
imagecopy($original, $watermark, ($osx-$wsx)/2, ($osy-$wsy)/2, 0, 0,
$wsx, $wsy);
imagepng($original, "apollo_trans.png");
?>
<html>
<body>
<table>
<tr><td align=center>Orignal Image</td><td
align=center>Watermark</td><td align=center>Orignal Image with
Watermark</td></tr>
<tr><td><img src="apollo.jpg"></td><td><img
src="xssportstransparent.png"></td><td><img
src="apollo_trans.png"></td></tr>
</table>
</body>
</html>
