[SOLVED] GD Image watermarking?

marksie1988 · December 27, 2007

i have tried variouse ways to watermark the image but cant seem to get it working, i have the below script which uploads and resizes the image and i am trying to get it to add a watermark after it resizes but everything i try doesnt work, i was wondering if someone could give me help with this as i am strugling to find something that will work with my script on the net or im just looking in the wrong places.

<?php

$errors = array(1 => 'php.ini max file size exceeded', 
                2 => 'html form max file size exceeded',

                4 => 'no file was attached');

$now = time();
while(file_exists($uploadFilename = $uploadsDirectory.$temp_filename))
{

$now++;

}
$username = $session->username;
    mysql_query ("UPDATE users SET pic = '$temp_filename' WHERE username = '$username'");



@move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadFilename)
