jQuery is one of the most used frameworks there is and it is renowned for being simple, flexible and easy to learn. There are literally hundreds, if not thousands of plugins to choose from. Here are a few plugins that I have previously used or would definitely use in the future. I hope you enjoy them!
jSquares is an image grid plugin which pops up an image and a description in an overlay. A good example would be the ted.com website. jSquares can be configured to suit your needs and works on all popular browsers.
Cloud Zoom is a jQuery image zoom plugin, a comparable alternative to products such as Magic Zoom. Compared to the popular jQZoom plugin, Cloud Zoom is smaller, has more features and more robust compatibility across browsers.
qTip is a very user-friendly robust enhanced tooltip with many features including rounded corners and speech bubbles.
WOW Slider is a jQuery image slider with stunning visual effects (Blast, Fly, Blinds, Squares, Slices, Basic, Fade) and tonnes of professionally made templates. WOW Slider is packed with a point-and-click wizard to create fantastic sliders in a matter of seconds without coding and image editing.
GalleryView aims to provide jQuery users with a flexible, attractive content gallery that is both easy to implement and a snap to customise.
jQuery Vertical Mega Menu
This plugin creates vertical mega menus using nested lists, which allow users to view all available menu options for each top-level menu item.
WowWindow is an advanced modal window script and Lightbox alternative, which allows you to create zooming windows from images, inline content, or videos (YouTube or Vimeo). It uses CSS3 transformations (rotate or zoom) to present the windows but still degrades sufficiently for browsers that do not support this.
