548730 Simple Web page Background changer script 2

I want a very simple javascript/php or java applet which will display all images inside a folder in form of thumbnails (small version of a large image) on a web page with their names at bottom in the same way windows does. Size of thumbnails can be adjusted with help of a slider. When user will click on a thumbnail that image will become background of the page. There will also be a option to set the next or previous image as the web page background and option to tile,stretch,fill,fit & center background image. This is how script will look like = [login to view URL]
