1) jQuery Cycle – We use this plugin primarily to handle rotating banners for our websites (as demonstrated here). This plugin has a huge number of options, display properties and transitions between slides.
2) jQuery maillink – This plugin is handy for hiding email addresses from bots that scrape web pages searching for email addresses to send spam to. Instead of having the typical and non-clickable format of jeff[at]tmprod.com or jeff@tmprod[dot]com, this plugin will take a span and render it into a clickable link on a page that will not be picked up by scrapers.

3) jQuery tweet! – Everyone wants to have a Twitter feed on their site these days. I’m a big fan of the tweet! plugin. It supports displaying tweets from multiple accounts, tweets from Twitter searches, Twitter lists, and a multitude of display options including pages and a scrolling ticker.
4) jQuery ColorBox – It seems every site these days has some sort of pop-up content. This is the plugin I use for this functionality. It can handle YouTube videos, images (both singular and groups of images), and even other html documents . Again, there is a good amount of customization that can be done to the way the pop-up displays with borders and shading and much more.
All of these plugins (and a few more) are included in almost every build we do here at Trademark Productions. They add great functionality without being difficult to use or understand. I’m always on the look-out for other great jQuery plugins. What ones do you use on a regular basis?
