you could setup say four different background images in your css and a
class for the properties:

randImg {
background-position: 100% 0;

imgOne {
background-image: url(imageone.jpg);
imgTwo {
background-image: url(imagetwo.jpg);
imgThree {
background-image: url(imagethree.jpg);
imgFour {
background-image: url(imagefour.jpg);

You could then setup an array for your images. 

imgArray = ["imgOne", "imgTwo", "imgThree", "imgFour"]

then use ASP to choose a random image from the array store it in randNumber.

and write the class into the page:

<div class="randImg <%= randNumber %>">

I dont know ASP so you'll have to excuse the code.
