redisplay image that was randomly chosen

[alvar]

this is killing me!

i have an image that is chosen randomly,
that is also used to display other images on mousing over a link. My question is, does anyone know how to get back the random image that was originally displayed?

function displayRandom()
{
var img_name = new Array("images/random/1.jpg", "images/random/2.jpg",
"images/random/3.jpg", "images/random/4.jpg")

var l = img_name.length;

var rnd_no = Math.round((l-1)*Math.random());

document.thumb.src = img_name[rnd_no];


}

the original image is random,
not the mouseover

dont see how i can use it
though, am i wrong?

i am a begginner in JS. . .

this is actually what i was looking for (myvar):

myvar = img_name[rnd_no];
document.thumb.src = img_name[rnd_no];
