Create image in gd library

Question

I am copying image over an image using GD library But it is not showing properly. This is my code:

<?php
$im = imagecreate(288,288);
$background_color = imagecolorallocate($im, 230, 248, 248);
$file = 'images/smiley/smile'.$_POST['smiley'].'.png'; 
$bg = imagecreatefrompng($file);
imagealphablending($bg, true); 
imagesavealpha($bg, true);
imagecopymerge($im, $bg, 10, 10, 0, 0, 100, 47, 25);
?>

i cannot upload image due to not enough reputation but i can explain that when i have a smiley where i have to overlap over an other image but when i run this function a grey color box overlap on the image instead of smiley. Smiley is also in grey color.

Please help...

This is the link for the image create after function runs

Try to set imagealphablending also for $im :

$im = imagecreate(288,288);
imagealphablending($im, true); 
$background_color = imagecolorallocate($im, 230, 248, 248);
$file = 'images/smiley/smile'.$_POST['smiley'].'.png'; 
$bg = imagecreatefrompng($file);
imagealphablending($bg, true); 
imagesavealpha($bg, true);
imagecopymerge($im, $bg, 10, 10, 0, 0, 100, 47, 25);
