Lightbox JS

Through the blog Ajaxian I found the announcement of Lightbox: a way to show thumbnails on and within your websites. With a click on this picture you receive a greater format as an overlay on top of the webpage.
You can even put a range of more than one image: a click on the first image shows you a projection of the first picture where you can scroll throughout the total image range.
The only possible improvement could be that when you start with for example the third picture you can only scroll till the last one. You can't go back to the first one.

I will certainly add thus to my website in due time.
