Widgetkit comes in two flavours, a free and a paid version. Both offer amazing widgets in a complete package, giving you a choice from a slider, spotlight overlays for images, tabs, accordions, map, lightbox, slidesets, media player, and even a Twitter widget. However, for anyone wanting to download and use the free version, you still get a lot of widgets rolled into a single plugin. This page showcases at least a couple of them, starting with a gallery that incorporates the spotlight overlay and the lightbox. The bonus here is that Encounters gives you a custom styling for Widgetkit.
WidgetKit Spotlight and Lightbox
This is a simple gallery using the Widgetkit plugin and two of it’s awesome features of Spotlight for the nice overlay when you mouseover each thumbnail, and then the Lightbox feature for viewing each image individually or as a slideshow. You can show photographs, illustrations, or even videos.
