**can help me please .. when i need to remove MAX_SIZE from my code and $dir='upload'; because function create thumbnail in images folder Nd i think error in this code

if(move_uploaded_file($t_name,$dir."/".$name)) {**

//define a maxim size for the uploaded images
define ("MAX_SIZE","1000");
// define the width and height for the thumbnail
// note that theese dimmensions are considered the maximum dimmension and are not fixed,
// because we have to keep the image ratio intact or it will be deformed
define ("WIDTH","250");
define ("HEIGHT","200");

// this is the function that will create the thumbnail image from the uploaded image
// the resize will be done considering the width and height defined, but without deforming the image
function make_thumb($img_name,$filename,$new_w,$new_h)
//get image extension.
//creates the new image using the appropriate function from gd library
if(!strcmp("jpg",$ext) || !strcmp("jpeg",$ext))


//gets the dimmensions of the image

// next we will calculate the new dimmensions for the thumbnail image
// the next steps will be taken:
// 1. calculate the ratio by dividing the old dimmensions with the new ones
// 2. if the ratio for the width is higher, the width will remain the one define in WIDTH variable
// and the height will be calculated so the image ratio will not change
// 3. otherwise we will use the height ratio for the image
// as a result, only one of the dimmensions will be from the fixed ones
if($ratio1>$ratio2) {
else {

// we create a new image with the new dimmensions

// resize the big image to the new created one

// output the created image to the file. Now we will have the thumbnail into the file named by $filename

//destroys source and destination images.

// This function reads the extension of the file.
// It is used to determine if the file is an image by checking the extension.
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;

// This variable is used as a flag. The value is initialized with 0 (meaning no error found)
//and it will be changed to 1 if an errro occures. If the error occures the file will not be uploaded.

if ($_POST['submit'])

if ($name)
// get the original name of the file from the clients machine
$file_upload = stripslashes($_FILES['file_upload']['name']);

// get the extension of the file in a lower case format
$extension = getExtension($file_upload);
$extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png"))
echo '<h1>Unknown extension!</h1>';

// get the size of the image in bytes
// $_FILES[\'image\'][\'tmp_name\'] is the temporary filename of the file in which the uploaded file was stored on the server

//compare the size with the maxim size we defined and print error if bigger
if ($sizekb > MAX_SIZE*904800)
echo '<h1>You have exceeded the size limit!</h1>';

//we will give an unique name, for example the time in unix time format
//the new name will be containing the full path where will be stored (images folder)

//we verify if the image has been uploaded, and print error instead

// the new thumbnail image will be placed in images/thumbs/ folder
// call the function that will create the thumbnail. The function will get as parameters
//the image name, the thumbnail name and the width and height desired for the thumbnail
