Here is tutorials of a fullscreen gallery with jQuery. The idea is to have a thumbnail of the currently shown fullscreen image on the side that flips when navigating through the images. The big image will slide up or down depending where we are navigating to. We will add navigation controls for the mousewheel and for keys. The thumbnail will have a zoom and and a fullscreen option, making the image in the background appear in fullscreen mode or as a complete image, resized to fit in the page.
