I have the following code to upload a pic

    	
if ($_SERVER['REQUEST_METHOD'] == "POST")
    { 
$size = 150; // the thumbnail height
$filedir = '../kill/'; // the directory for the original image
$thumbdir = '../uploads/'; // the directory for the thumbnail image
$prefixct= $_POST['PartNum']; // the prefix to be  added to the original name
$prefixpn = '-';
$maxfile = '512000';
$mode = '0666';


$userfile_name = $_FILES['image']['name'];
$userfile_tmp = $_FILES['image']['tmp_name'];
$userfile_size = $_FILES['image']['size'];
$userfile_type = $_FILES['image']['type'];
    if (isset($_FILES['image']['name']))
     	{
         	$prod_img = $filedir.$userfile_name;
         	$prod_img_thumb = $thumbdir.$prefixct.$prefixpn.$userfile_name;
             $mysqlpath=$prefixct.$prefixpn.$userfile_name;
         	move_uploaded_file($userfile_tmp, $prod_img);
         	chmod ($prod_img, octdec($mode));
         	$sizes = getimagesize($prod_img);
         	$aspect_ratio = $sizes[1]/$sizes[0];
         	   if ($sizes[1] <= $size)
         	   {
                $new_width = $sizes[0];
                $new_height = $sizes[1];
         	   }else{
                $new_height = $size;
                $new_width = abs($new_height/$aspect_ratio);
         	   }

$destimg=ImageCreateTrueColor($new_width,$new_height) or die('Problem In Creating image');
$srcimg=ImageCreateFromJPEG($prod_img) or die('Problem In opening Source Image');
ImageCopyResized($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srcimg),ImageSY($srcimg)) or die('Problem In resizing');
ImageJPEG($destimg,$prod_img_thumb,90) or die('Problem In saving');
imagedestroy($destimg);

     		}

This works fine - What I am having a problem with is adding the $_POST['PartNum']; as a prefix to the original image - any thoughts? (either before or after making the thumb.

Cheers

[php]$prefixct= $_POST['PartNum'];//
$prefixct = ''; // the prefix to be added to the original name
[php]

You do realize that the second one overwrites the first right?

Yeah sorry - the code moved the original was on the same line as //

SOLVED

move_uploaded_file($userfile_tmp, $prod_img);

Change this to any file name

If I understand you correctly. Are you trying to change the original image name into something else... If so..
You will have to change it before you convert it into a thumbnail.
To do this I would use the explode() function to break appart $_FILES['image']['name'];

example
$_POST['name'] = 'myimage';
$_FILES['image']['name'] = 'imagename.jpg';

$x = explode(".", $_FILES['image']['name']); // It breaks appart name and converts to an array

$x[0] //imagename
$x[1] //jpg

$newname = $_POST['name'] "." $x[1]; //myimage.jpg

$_FILES['image']['name'] = $newname;

Then perform the rest of your code...
