Lightview is a jQuery plugin for creating overlay windows (lightboxes).
It features an easy-to-use API and extra media support which is sometimes lacking in other LightBox plugins.
What’s interesting about Lightview is how comprehensive the library is.
It features a powerful API, skinning, callbacks, and has more options than a regular user would need… ever.
Lightview is quite the heavyweight in terms of size, too: ~130kb for all required files.
The license is free for non-commercial use, and licensing for commercial projects starts from 50EUR.
