"Random non-random" image generator

Hi all -

This seems to be a great forum and I'm sure someone here can help me.

I'd like to have a sort-of-random image generator. I have the code for a random image generator, and that's fine, but sometimes I want to show a certain image more than others. I hope I'm explaining this clearly...say I have 11 images, and I want one of them to show up 50% of the time and the other 10 to show up 5% of the time each. I would think this is pretty simple for a good coder, but that ain't me.

Thanks!

If you're using the JS code that I've used.... why not just repeat the entry twice?

There IS a way to do it with percentages, but if your random coding is already in place, to reason to repaint the room. Like this:

Code:

<!-- Hide from old browsers
var imagenumber = 4 ;
var randomnumber = Math.random() ;
var rand1 = Math.round( (imagenumber-1) * randomnumber) + 1 ;
images = new Array
images[1] = "images/01.jpg"
images[2] = "images/02.jpg"
images[3] = "images/03.jpg"
images[4] = "images/03.jpg"
var image = images[rand1]
// -- End Hiding Here -->

Thanks laura, very simple solution. I think that'll work for me.

Thanks again!
