In this tutorial we will create an image gallery with jQuery that shows a preview of each image as a little thumbnail. The idea is to hover over the slider dots and make the regarding thumbnail slide into the previewer. When clicking a slider dot, the full image will slide in from the right or left side, depending on the currently viewed image.
Update: If you are interested in integrating the thumbnails preview slider you might want to check out the new post on how to use only the preview part.
