You can visit http://docs.jquery.com/Downloading_jQuery and get a link to a CDN (Content Delivery Network). In this case, you could use the Microsoft CDN. Make sure to copy the link. In the case that you want to save a copy of the file in your website, you can get the latest version of jQuery from jquery.com. Visit the website and look for "Grab the Latest Version" header. Select the production checkbox, click on the download button and save to your computer. This should save the minimized (no spaces, no comments, lighter in size) version of the File. Once you have the copy on your workstation, you can login to your Office Live administration website and upload the file to your document gallery.

There is the need for a custom script which will be used to manipulate the web page. This is part of a different blog which I will be providing soon.
