Merge two PNG images with PHP GD library

by 
$image1 = imagecreatefrompng('a.png'); //300 x 300
$image2 = imagecreatefrompng('b.png'); //150 x 150
imagecopymerge($image1, $image2, 0, 0, 75, 75, 150, 150, 50);

this should be all you need. $image1 should hold the merged image where image2 has been overlayed with 50% opacity. the last argument is the alpha of the merged copy.
