Hi,

 

i have a script that allows my users to upload am image onto my website, i am looking at modifying it so that it can resize the image and then add a watermark to it, i know that i need to use gd to do this but have never used gd before and dont know where to add the gd code into my script.

 

i have guessed also that once i know how to add the gd for resizing the image i will be able to work out the watermark for myself so where do i add gd script and what would i need to resize >??? my code is below.

 

<?php 
include("../login/include/session.blc");
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']);
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'userpics/';
$uploadForm = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.form.blc';
$uploadSuccess = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.success.blc';
$fieldname = 'file';
$errors = array(1 => 'php.ini max file size exceeded', 
                2 => 'html form max file size exceeded', 
                3 => 'file upload was only partial', 
                4 => 'no file was attached');

isset($_POST['submit'])
or error('the upload form is needed', $uploadForm);

($_FILES[$fieldname]['error'] == 0)
or error($errors[$_FILES[$fieldname]['error']], $uploadForm);

@is_uploaded_file($_FILES[$fieldname]['tmp_name'])
or error('not an HTTP upload', $uploadForm);

@getimagesize($_FILES[$fieldname]['tmp_name'])
or error('only image uploads are allowed', $uploadForm);

$now = time();
while(file_exists($uploadFilename = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name']))
{

$now++;

}
$username = $session->username;
$pic = $now.'-'.$_FILES[$fieldname]['name'];
    mysql_query ("UPDATE users SET pic = '$pic' WHERE username = '$username'");
@move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadFilename)
or error('receiving directory insuffiecient permission', $uploadForm);
header('Location: ' . $uploadSuccess);

function error($error, $location, $seconds = 5)
{
header("Refresh: $seconds; URL=\"$location\"");
echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"'."\n".
'"http://www.w3.org/TR/html4/strict.dtd">'."\n\n".
'<html lang="en">'."\n".

'		<span class="red">' . $error . '...</span>'."\n\n".
'	 	The upload form is reloading</p>'."\n\n".
'	 </div>'."\n\n".
'</html>';
exit;
}
