Add error checking. Turn on error_reporting(E_ALL) (http://php.net/error_reporting) and var_dump() (http://php.net/var_dump) everything.

line 230 is the error_reporting(E_ALL) and var_dump()

You.... misunderstood. The error_reporting function goes at the top, and you var_dump the returns from functions, or variables which you expect to be correct.

if (function_exists(imagecreatetruecolor)){
Should be:

if (function_exists('imagecreatetruecolor')){
That is what is causing those undefined constant notices. The warning is because you still aren't using var_dump() properly. Go to the point where you think you have a problem, and
var_dump($the, $variables, $you, $are, $using, $so, $you, $can, $see, $what, $their, $values, $are); You can also
var_dump(functions_you_are_calling($with, $their, $params));

I have a script that does similar to this... it's a little more compact though. A basic run down of it is.

1. I upload 1 file to a temp folder. This is the base image I use to create the thumbnails.
2. I create the main image (which is a smaller version of the original).

3. I create the thumbnail image, which is created from the original image.

4. I unlink the temp base image to remove it from the server (as to conserve space).

My Code... it's a little rough because of the mysql and various error checking, and type checkings but she works good. I added comments so you can understand it better.

function addImage($id,$type="") {
global $_FILES, $config;
//Path to oringinal file.
$start = $config["path"]."examples/web_design/".$id.".jpg";
//Upload original file
copy($_FILES['image']['tmp_name'], $start);
//Path to larger thumbnail
$large = $config["path"]."examples/web_design/".$id."_lg.jpg";
//Path to smaller thumbnail
$small = $config["path"]."examples/web_design/".$id."_sm.jpg";
//Path to even smaller thumbnail
$featured = $config["path"]."examples/web_design/featured/".$id.".jpg";
//Call thumbnail function to make thumbnails.
