Adding a Shaddow

[NZ_Kiwis]

I have two seperate codes
Code 1;

This is my working resize code, needs to stay like this as it's a remote image.

<?php
if ($size == "") {
$size = "M";
}

$off_site = "BKK/10.jpg"; 
$fp = fopen ($off_site, 'rb') or die('Unable to open file '.$off_site.' for reading');  

$buf = ''; 
while (!feof ($fp)){  

$buf .= fgets($fp, 4096);  

}  

header('Content-Type: image/jpeg'); 
$data = $buf; 

$src = imagecreatefromstring ($data); 
$width = imagesx($src); 
$height = imagesy($src); 
$aspect_ratio = $height/$width; 


if ($height < $width) { 
$new_w = 640; 
$new_h = 480; 
} else { 
$new_h = 640; 
$new_w = 480; 
} 

$img = imagecreatetruecolor ($new_w,$new_h);  

imagecopyresampled ($img,$src,0,0,0,0,$new_w,$new_h,$width,$height);  

imagejpeg($img, '', 90);  

imagedestroy($img); 
}
?>

Code 2;

This works for images on the same site, problem is I'm having major problems taking the shadow parts of this code out and adding it to the above code...

list($width, $height) = getimagesize($filename);
$newwidth = "640";
$newheight = "480";
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($filename);
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

define("DS_OFFSET",  5);
define("DS_STEPS", 10);
define("DS_SPREAD", 1);

$background = array("r" => 255, "g" => 255, "b" => 255);
$filename = isset($_REQUEST['filename']) ? urldecode($_REQUEST['filename']) : null;
if(isset($filename) && file_exists($filename)) {


$width  = $newwidth + DS_OFFSET;
$height = $newheight + DS_OFFSET;
$image = imagecreatetruecolor($width, $height);

$step_offset = array("r" => ($background["r"] / DS_STEPS), "g" => ($background["g"] / DS_STEPS), "b" => ($background["b"] / DS_STEPS));

$current_color = $background;
for ($i = 0; $i <= DS_STEPS; $i++) {
$colors[$i] = imagecolorallocate($image, round($current_color["r"]), round($current_color["g"]), round($current_color["b"]));

$current_color["r"] -= $step_offset["r"];
$current_color["g"] -= $step_offset["g"];
$current_color["b"] -= $step_offset["b"];
}
imagefilledrectangle($image, 0,0, $width, $height, $colors[0]);

for ($i = 0; $i < count($colors); $i++) {
imagefilledrectangle
($image, DS_OFFSET, DS_OFFSET, $width, $height, $colors[$i]);
$width -= DS_SPREAD;
$height -= DS_SPREAD;
}

imagecopymerge($image, $thumb, 0,0, 0,0, $newwidth, $newheight, 100);
header("Content-type: image/jpeg");
$image2 = imagerotate($image, $degrees, 0);
imagejpeg($image2, "", 100);
imagedestroy($image2);
imagedestroy($original_image);
}

Can someone please help.

Sure. Try to combine them again, and show us your erraneous hybrid of the two snippets, and we can try to show you where you went awry.

I just get the red X

<?php

$width = imagesx($src); 
$height = imagesy($src); 
$aspect_ratio = $height/$width; 


if ($height < $width) { 
$new_w = 960; 
$new_h = 720;

}

Perhaps PHP is trying to give an error? Comment out the header() line and make sure error_reporting is set to E_ALL (and that display_errors is set to On, of course).

But then... look at this line:

$filename = isset($_REQUEST['filename']) ? urldecode($_REQUEST['filename']) : null;

Is the filename really in the request array now? Above, you have a URL defined in the script. Is this hard-coded example actually part of the script, or are you going to be pulling a filename from a REQUEST variable? Choose one.

EDIT: I see you've edited the code and removed the two different imagejpeg() calls, so I've edited my post above accordingly :p

OKay I removed this but now the shadow is just black... how can this be fixed?

$off_site = "http://www.site.com//BKK/10.jpg";

Should there only be one / between com and BKK???

Hmmmm as you can see I've changed my URL, but sorry i didn't take out the extra /... not that this would make a difference
