Definitely one of my favorite slideshow. Based on Mootools, Noobslide allows numerous variations and customization, despite of its lack of offical documentation.
Accessible News Slider
Sadly, it could be a bit hard to personalize it. If you’re interested in a tutorial, just ask in the comments!
jQuery Multimedia Portfolio
Based on JQuery, jQuery Multimedia Portfolio can handle a large variety of media : text, photos, but also flv videos and mp3 audio and is simple to use. A good script.
jCarousel is a jQuery plugin for controlling a list of items in horizontal or vertical order. The items, which can be static HTML content or loaded with (or without) AJAX, can be scrolled back and forth (with or without animation). JCarousel is very complete, allowing you to creates vertical slideshows, text-scrollers, circular carousels, custom animations, and can be used together with Thickbox.
I never used it personally on a project, but I can’t wait to try it out!
Inspired by the carousel you can see on panic.com, here’s Glider, a Prototype/Script.aculo.us based slideshow. A really cool use of Glider has been done on the amazing WP Magazine Theme for WordPress.
Using YUI (Yahoo User Interface), this basic carousel is semantically coded (HTML LI elements within a UL), and allows you to display your content horizontally or vertically.
A simple but good carousel, if you just need the basic effects.
