Auto thumnailer problems

[spyke01]

I need to create 2 different sized thumbnails automaticly from an image being uploaded, the databas insertion works fine, but after the first image is uploaded, the other two never get made. I only get a dialog box saying that the script on the page is taking too long to execute and asks if i want to stop it or continue.

I added echo statements in but the script wont print past some basic html for the menus

page:
[code]
<?php


include "includes/header.php";



//=====================================================

// If the user is not logged in redirect them

//=====================================================

if (!isset($_SESSION[user_level])) {

// User is not allowed in the admin section, kick them out

echo "\n You do not have sufficient access rights to access this section, or you are not logged in. You are being redirected to the login page.<br />";

echo "\n If you are not redirected automaticly, please click <a href=\"$menuvar[LOGIN]\">here</a>.<br />";

echo "\n <meta http-equiv='refresh' content='1;url=$menuvar[LOGIN]'>";

}

//=====================================================

Im not advanced at php but you should set the thumbnail image height and width (make it smaller ). Then set the default height and width when you want to view the image. Hope this helps.

that would still be one image, the large one, i need to actually create the smaller ones for a shorter load time
