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:
<?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]'>";

	} 

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

	// If the user is an employee the print the page

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

	else {

		if ($_SESSION[user_level] != ADMIN && $_SESSION[user_level] != EDITORS && $_SESSION[user_level] != STREET_TEAM) {

			echo "\n			You do not have sufficient access rights, please contact an administrator.";

		}

		else {

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.
