[removed] random image selected on refresh

Question

So I have a site in which I have a description area and I have it be a random description on refresh by using the following code:

Answer 1

How about:

HTML:

JS:

var description = [
  "http://static.ddmcdn.com/gif/lightning-gallery-17.jpg",
  "http://static.ddmcdn.com/gif/lightning-gallery-18.jpg",
  "http://static.ddmcdn.com/gif/lightning-gallery-19.jpg",
  "http://static.ddmcdn.com/gif/lightning-gallery-20.jpg",
  "http://static.ddmcdn.com/gif/lightning-gallery-21.jpg"
];

var size = description.length
var x = Math.floor(size*Math.random())
document.getElementById('image').src=description[x];

No jQuery necessary.
