image to css / html file

I want to convert this image into a css/html page Requirements: 1) standards compliant, look the same in all modern browsers including: Chrome, firefox, IE, Safari 2) background should stretch, proportionally, to fill background as browser window stretches Ive seen methods of scaling using various methods, any recomendations to lower file size but keep quality? 3) I want a preload script that stores all background images in users cache, but only after a delay of 5 seconds, so the whole page can load first 4) background images should change randomly on page load, from a folder of images 5) Use css not tables 6) Notice the translucent effect, i want to keep this even when the background image changes.
