Where can I find jQuery plugins?
jQuery.com has an extensive library of jQuery plugins (they invented the programming language, after all). Additionally, Unheap.com is another fantastic resource for beautiful, easy to use jQuery plugins.
One of my favorite plugins found through Unheap is the Strip Lightbox. This plugin creates a light box that only covers part of the page, which allows you to continue to interact with the web page, and also providesa less intrusive image viewing experience.
