upload banner ad rotator to existing site

  javascript, jquery, plugins

I’ve purchased a jquery banner ad rotator from Codecanyon because I want to have an auto-rotating ad banner on the home page of my classified ads website (OSCLASS).

My problem is, I have no idea where about in my website the script files should be uploaded to (e.g, which folders?). Also wondering if there are any files I need to downlaod first to make this script work. Anyone with an idea how this is done?
