Merging images while preserving transparency

[Tyilo]

I have tried many solution, but nothing seems to fix this.

The problem is that i put an image with transparency on top of another image, but the transparent pixels still transparent, where they should show some of the image below it.

 

If you call it with l=100 and p=20 i would get this result http://cl.ly/566Z instead of this http://cl.ly/56OF.

 

Here is the source code and I have attached the images:

<?php
header('Content-type: image/png');
echo imagepng(progressbar($_GET['l'], $_GET['p']));
function progressbar($length, $percentage)
{
$length = round($length / 2) * 2;
$percentage = min(100, max(0, $percentage));
if($length > 0)
{
	$bar = imagecreate($length, 14);
	imagealphablending($bar, false);
	imagesavealpha($bar, true);
	$empty = imagecreatefrompng('Empty.png');
	imagealphablending($empty, false);
	imagesavealpha($empty, true);
	$fill = imagecreatefrompng('Fill.png');
	imagealphablending($fill, false);
	imagesavealpha($fill, true);
	$lempty = imagecreatefrompng('LeftEmpty.png');
	imagealphablending($lempty, false);
	imagesavealpha($lempty, true);
	$lfill = imagecreatefrompng('LeftFill.png');
	imagealphablending($lfill, false);
	imagesavealpha($lfill, true);
	$rempty = imagecreatefrompng('RightEmpty.png');
	imagealphablending($rempty, false);
	imagesavealpha($rempty, true);
	$rfill = imagecreatefrompng('RightFill.png');
	imagealphablending($rfill, false);
	imagesavealpha($rfill, true);
	$emptycaplength = min(7, $length / 2); //5 
	imagecopy($bar, $lempty, 0, 0, 0, 0, $emptycaplength, 14);
	imagecopy($bar, $rempty, $length - $emptycaplength, 0, 7 - $emptycaplength, 0, $emptycaplength, 14);
	if($length > 14)
	{
		imagecopyresized($bar, $empty, 7, 0, 0, 0, $length - 14, 14, 1, 14);
	}
	$filllength = round(($length * ($percentage / 100)) / 2) * 2;
	$fillcaplength = min(7, $filllength / 2);
	imagecopy($bar, $lfill, 0, 0, 0, 0, $fillcaplength, 14);
	imagecopy($bar, $rfill, $filllength - $fillcaplength, 0, 7 - $fillcaplength, 0, $fillcaplength, 14);
	if($filllength > 14)
	{
		imagecopyresized($bar, $fill, 7, 0, 0, 0, $filllength - 14, 14, 1, 14);
	}
	imagealphablending($bar, true);
	return $bar;
}
else
{
	return false;
}
}
?>
