Finally I found a good light-box which really matches the name “Light box” in FancyBox.It is a jQuery based light window. It has very less features while compare with any other light box, but simple to use. Compatible with all browsers.
Go here to find it : http://fancybox.net/
The window automatically resize with image. If you put title attribute, it shows the title below with the light window.
Instead of image, you can point a file. If you need to open that file in iframe, use class=“iframe”
