Image upload *was* working, now isn't, a solution?

[tjhilder]

Hi, this script used to work, but i'm not sure why it isn't now.

 

this script basicly uploads an image, makes a thumbnail of it, then uploads some info into a database.

<?php
            define ("MAX_SIZE","100");
            define ("WIDTH","150");
            define ("HEIGHT","100");

            function make_thumb($img_name, $filename, $new_w, $new_h)
            {
               $ext = getExtension($img_name);
               if(!strcmp("jpg", $ext) || !strcmp("jpeg", $ext))
               {
                  $src_img = imagecreatefromjpeg($img_name);
               }
               if(!strcmp("png", $ext))
               {
                  $src_img = imagecreatefrompng($img_name);
               }
               if(!strcmp("gif", $ext))
               {
                  $src_img = imagecreatefromgif($img_name);
               }

               $old_x = imageSX($src_img);
               $old_y = imageSY($src_img);

               $ratio1 = $old_x / $new_w;
               $ratio2 = $old_y / $new_h;
               if($ratio1 > $ratio2)
               {
                  $thumb_w = $new_w;
                  $thumb_h = $old_y / $ratio1;
               }
               else
               {
                  $thumb_h = $new_h;
                  $thumb_w = $old_x / $ratio2;
               }

               $dst_img = ImageCreateTrueColor($thumb_w,$thumb_h);

               imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0, $thumb_w, $thumb_h, $old_x, $old_y);

But when I try to run this script, I get these errors:

$config_gallery_dir and $config_thumbnail_dir are located in an external config.inc.php file and as far as I know are not pointing to the wrong area because it uploads the image fine.
