iBox is a lightweight script that lets you overlay images and documents in a small dialog without a page reload. It's built to be easy to install and use, while offering great flexibility.

iBox easily supports the standard overlay of images, in many sizes, and will automatically scale down the window if the browser's viewpane is too small.

iBox supports overlaying documents as well as the standard images. This is achieved in the same fashion as an image, but instead of showing the image, it shows the document you are linking to. Support is also given for embedded containers so you don't need to perform a page request for a document.
