help needed

[Marty McFly]

i need a javascript so that every time i refresh the page the logo will change. I have already uploaded the images. I have four images that i wish to use.

can any one help?

1. put the images names in an array
2. get a random number using
Math.random()
3. make sure you don't get random number greater then your array length
4. every time page loads create image that matches the random number in the array index

Here's some code (JavaScript) for ya:

<script language=JavaScript>
var image_num = Math.floor(Math.random() * 4) + 1;
if (image_num==1) {
document.write("<img src='you_first_random_image_src'>");
}
if (image_num==2) {
document.write("<img src='you_second_random_image_src'>");
}
if (image_num==3) {
document.write("<img src='you_third_random_image_src'>");
}
if (image_num==4) {
document.write("<img src='you_fourth_random_image_src'>");
}
</script>

Just place this code where you wan't your images to appear. And of coarse change the src's of the img tags to wan't you wan't and there you go.

And what happens when JS is disabled? That script above is about the worst way to accomplish the task.

Yes, JS can be disabled, but the point is, is that he asked for JavaScript, so.
