I’ve compiled reference articles for using jQuery’s ThickBox.

Basically, reading the official site is sufficient.

・Official (English): ThickBox 3.1

If you’re not good with English, you might want to read Japanese reference sites to roughly understand the usage before reading the official site.

・jQuery Version of LightBox “ThickBox” [to-R]

・Late to the Party: jQuery Plugin ThickBox3.1 - Webtech Walker

That’s all from the Gemba.
