QJqDock

The Dock - as anyone familiar with a Mac will know - is a set of iconic images that expand when rolled over with the cursor, and usually perform some action when clicked. This plugin mimics that behaviour by transforming a contiguous set of HTML images into an expanding Dock, vertical or horizontal, with or without labels.

Basically, all the Dock does is smoothly expand a reduced size image towards its full size when the cursor is on or near it. You can specify a vertical or horizontal orientation for the Dock, and select the direction in which the image should expand and whether to show labels or not. The styling and positioning of the Dock is (almost) entirely up to you.

If you want to learn more about this plugin, check out the jqDock plugin homepage - it has a detailed description of the various options that you can set to control the style of the Dock.
