By using the Google API Library you can speed up your store by using Google’s content framework network.  Google offers high-speed and global access to many Javascript frameworks, including jQuery, which CS-Cart uses.

You will need to edit one .tpl file for this to work.

Open the file “common_templates/scripts.tpl” and look for this line

{script src="lib/jquery/jquery.js"}

You can replace this line with Googles direct link

{script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"}
