Merging images doesn't work

[Ishimoto]

Hi,

I'm trying to combine two images - an uploaded image and a permanent. First I try to resize them to the same dimensions. Why I resize the uploaded image to the dimensions of permanent, everything works fine. But when I do the opposite, the images just don't merge, and the output is just the permanent image with resized dimensions. Anyone knows why?

Here is my code:

<?php
if( isset( $_FILES['image'] ) ){
	$desired_width = 360;
	$desired_height = 360;

	$layers = array();
	switch($_FILES['image']['type']){
		case "image/jpeg":
			$source_image = imagecreatefromjpeg($_FILES['image']['tmp_name']);
		    break;
		case "image/gif":
			$source_image = imagecreatefromgif($_FILES['image']['tmp_name']);
			break;
		case "image/png":
			$source_image = imagecreatefrompng($_FILES['image']['tmp_name']);
			break;
	}
	
	$frame = imagecreatefrompng("1.png");
        $desired_width = imagesx($source_image);
        $desired_height = imagesy($source_image);
        $virtual_image = imagecreatetruecolor($desired_width, $desired_height);
        imagecopyresampled($virtual_image, $frame, 0, 0, 0, 0, $desired_width, $desired_height, 360, 360);

	$layers = array($source_image,$virtual_image);

	$image = imagecreatetruecolor($desired_width, $desired_height);

	// to make background transparent
	imagealphablending($image, false);
	$transparency = imagecolorallocatealpha($image, 0, 0, 0, 127);
	imagefill($image, 0, 0, $transparency);
	imagesavealpha($image, true);

	imagealphablending($image, true);
	for ($i = 0; $i < count($layers); $i++) {
	    imagecopy($image, $layers[$i], 0, 0, 0, 0, $desired_width, $desired_height);
	}
	imagealphablending($image, false);
	imagesavealpha($image, true);

	header('Content-type: image/png');
	header('Content-Disposition: attachment; filename="new_profile.png"');
	imagepng($image);
}
?>
