Caja ligera

Este Lightbox liviano pesa solo 6500 bytes, pero le permite mostrar imágenes en una variedad de formas con una interfaz increíblemente simple.

Our light box control is a light weight JavaScript plugin that works with any site, and comes as standard as part of our Ousia Content Management System.

It will work well in any of four ways;

Plain image
Image with caption text
Image wrapped in a hyperlink
Image wrapped in a hyperlink with caption

We've set some examples below, and provided all of the code you need to get it up and running.

If you use this in any code then please give us a mention somewhere in your site.
