From the blog: "Recently I had a project that demanded a rollover image preview. You know, one of those tooltip-like bubble popups that appears when you roll over link or a thumbnail. Since we were already using jQuery on that project I decided to take it easy and investigate what can be done with that extraordinary library. So I came up with a script so simple it hurts! The best thing yet is that it can be applied for a variety of purposes."
This is very, very nice and looks easy, too. The three versions are packaged together for easy download or you can copy and past from the blog.
Version One: The Simplest jQuery Tooltip Ever
Version Two: Image Preview Gallery
Version Three: Links With URL Preview
