Templating System, almost done just need a kick over top

Hi, I am designing a basic templating system and its almost finished, just a couple of tweaks and security upgrades are needed. What I need is this: Mod rewrite on three pages through .htaccess Need a cookie for the backend blog system to keep the username and password on the user machine for 1 hour or when they close the page Small changes in the blog system backend Security for the image upload system and the blog system, no direct access via .htaccess Make the page title change with the page (cant figure that out) on the image upload thankyou page make a redirect back to the image upload script Any security flaws that you might find on the site This site is based of php and the blog system saves the blogs in mysql. There is no style on the site at the moment, just trying to get the code right first. Thats about all I need done for this site. Thanks
