I was impressed this morning by the smooth swipe of the graphics on the BK splash page: http://www.bk.com/ Can anyone point me to a page where I might get some javascript that can do something like this? What kind of language does one even use to describe this so I might search it up on my own? Thanks.
You could find something similar on codecanyon.com for cheap. It seems to be a fairly simple jQuery slider.
You might like this jQuery plugin http://www.buildinternet.com/project/supersized/. Most of such toys is based on jQuery ( javascript framework ) I really recommend to know basics of jQuery if you are in webmastering. Such background slideshows should be based on AJAX to save bandwitch. It is bad practise to load all the pictures at start. Each another picture in the queue should be loaded only at time when needed. It can be achieved using AJAX - jQuery has very simple functions to handle AJAX loading.
