I dont know where else to turn.... this script is supposed to read all of the images in a directory, determine if the directory has a thumbnail folder, if not, it is supposed to create one and create thumbs for all of those images and then display the images in a table until there are no more left.  THe script is short, but I keep getting error messages.

Warning: imagecreatetruecolor(): Invalid image dimensions in /home/christop/public_html/illustrations/read_dir.php on line 22

Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /home/christop/public_html/illustrations/read_dir.php on line 23

Warning: imagejpeg(): supplied argument is not a valid Image resource in /home/christop/public_html/illustrations/read_dir.php on line 24
./bub.jpg

Please help.

---------------------------- The Script I have so far...................................................

<?php

    while (false !== ($file = readdir($handle))) {
        if ($file != '.' && $file != '..' && eregi(".jpg",$file)) {
// $allpics[] = $file; // simply list all the pics in an array (without extension) for later saving
$allpics[] = $path.$file;
}
    }
    closedir($handle);
}

foreach ($allpics as $item) {
$thumbnail_path = add_folder_to_directory_path($item,"thumbs");

if (!is_file($thumbnail_path)) {
// if there is no file in the thumbs directory
createThumbnail($item); // CREATE FUNCTION

}
echo $item;
}

$newfolder = add_folder_to_directory_path($oldfolder, "thumbs");

You havn't defined $thumbWidth

I figured that would be determined by each file that is in the directory when the script reads them.
