GD Error

[NZ_Kiwis]

My image will not show when i try shrink it to show within a window

<?php
$filename = "../item-img/" . $_GET['file'];

// Content type
header('Content-Type: image/jpeg');

// Get new sizes
list($width, $height) = getimagesize($filename);

$percent = 0.99;
do {
	$percent = $percent - 0.01;   

	$newwidth = $width * $percent;
	$newheight = $height * $percent; 

} while ($newwidth > 267 && $newheight > 200);



// Load
$thumb = imagecreatetruecolor(267, 200);
$white = imagecolorallocate($thumb, 255, 255, 255);
imagefill($thumb, 0, 0, $white);

$source = imagecreatefromjpeg($filename);

// Resize
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

// Output
imagejpeg($thumb);

Are you getting an error (either on-screen [view source]) or in the PHP error log)? Out-of-memory errors are not uncommon when using GD, especially as images get larger, since it builds a bitmap of the image in memory, where it's something like 4 bytes width height (might be 8 bytes per pixel, don't remember off the top of my head for sure).

This will be tricky to debug unless you can get a look at the errors which get generated. Obviously, if you are referring to the output of this image in an <IMG> tag, then you won't see the errors. Try accessing the script directly.

You might also want to check for errors and whether your function calls return proper objects or whether they return FALSE.
