How Do I Install Theme From Computer

I saw a great theme on google android and it wont (or I cant) download directly to my Android...It will and has downloaded to a zip file on my pc...How in the world do I get this on my phone? I am jailbroken. Maybe I can find it thru cydia? heres the page link and theme I'm trying to get..

iGoogle Cool FOR HD Android theme free download, Android 3gs theme,Android 4 theme,Android FOR HD theme for free download

Any and all help is tremendously appreciated.

It appears I need to figure out this SSH thing..
