FancyBox is another lightbox but according to it’s author it’s “something fresh and Mac-like”. Uses jQuery.

Features:

* Automatically scales large images to fit in window
* Adds a nice drop shadow under the zoomed item
* Groups related items and adds navigation through them (uses preloading)
* Can display images, inline and iframed content
* Customizable through settings and CSS

Shadowbox.js Media Viewer is a “cross-browser, cross-platform, cleanly-coded and fully-documented media viewer application written entirely in JavaScript”. So no MooTools or Prototype needed. Interesting, worth a look.

Lightview is a new lightbox implementation (ok it might not be new, but it’s new to me and recently updated). Requires Prototype 1.6 and uses Scriptaculous. I love the rounded corners (without using PNGs apparently), especially when it’s used for a photo slideshow. Bookmarking because I haven’t seen this lightbox yet and want to give it a test-drive.
