Problem with imagecreating through php

Bootsman123

<?php
$factor = 4;
$base_dir = "images";

if ($dir = opendir($base_dir)) {
	while (false !== ($file = readdir($dir))) {
		$read_dir = "$base_dir/$file";
		if ($file != "." && $file != ".." && !preg_match("/(.*?)thumbnail_(.*?)/si", $file)) {
			$image_info = getimagesize($read_dir);
			$image_info[0] = $image_info[0]/$factor;
			$image_info[1] = $image_info[1]/$factor;
			$image_org = imagecreatefromjpeg ($file);
			$new_thumbnail = imagecreatetruecolor ($image_info[0], $image_info[1]);
			imagecopyresized ($new_thumbnail, $image_org, 0, 0, 0, 0, $image_info[0], $image_info[1], imagesx($image_org), imagesy($image_org));
			$new_file_name = "thumbnail_" . $file;
			imagejpeg($new_thumbnail, $base_dir."/".$new_file_name, 85);
			imagedestroy ($new_thumbnail);
			echo "<p>Succes!";
		}
	}
}
?>

I'm trying to make a script that loops through a directory and checks if there isn't made a thumbnail of a picture. If so it should create a thumbnail. It does create a thumbnail, but it the thumbnail is just plain black. Any help would be appreciated.

It's got to be something with your configuration. I'm not quite sure how to use imagecreatetruecolor(), but I do know that your code is correct. (That is, correct for GD1.)

Sorry I can't really help further, though.

imagecreatetruecolor doesn't will not work on anything less than GD 2.0 Don't know what version you are using

He's probably using 2.x, which explains why he can use it.

I, however, can't, since I'm on GD1, which is why I couldn't test his script for validity.

i have GD2 and the code works fine with one change

this line

$image_org = imagecreatefromjpeg ($file);

needs to be changed to

$image_org = imagecreatefromjpeg ($read_dir);

it breaks on this line

It should work fine as long as $base_dir is set to "." (current).

Thanks a lot, it worked! I'm sorry I didn't told which version of GD I used, it would've been a bit easier for you to find my problem.
