random slide of images, and menu on top

random slide of images, and menu on top

now you see a rectangular beam with image inside and the 4 menu items on the right, now, I would like to be the 4 menu items, but replace the fixed image background with a random sequence of images, with fade in transition from one image to another.
Is it possible? and with which jquery gallery (free)?
The home page is www.renderit.it

thank you very much
