Random Image

John Able Jun 22, 2001

Use this script to randomly display a different image each time the page is visited. Refresh this page and notice the image below will change. Any number of images can be used, and set-up is very easy.

The JavaScript Source: Miscellaneous: Random Image

Simply click inside the window below, use your cursor to highlight the script, and copy (type Control-c or Apple-c) the script into a new file in your text editor (such as Note Pad or Simple Text) and save (Control-s or Command-s). The script is yours!!!

<!-- TWO STEPS TO INSTALL RANDOM IMAGE:

1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  -->

<HEAD>

<!-- Begin
// Set up the image files to be used.
var theImages = new Array() // do not change this
// To add more image files, continue with the
// pattern below, adding to the array.

theImages[0] = '1.gif'
theImages[1] = '2.gif'
theImages[2] = '3.gif'
theImages[3] = '4.gif'

// do not edit anything below this line

var j = 0
var p = theImages.length;
var preBuffer = new Array()
for (i = 0; i < p; i++){
   preBuffer[i] = new Image()
   preBuffer[i].src = theImages[i]
}
var whichImage = Math.round(Math.random()*(p-1));
function showImage(){
document.write('<img src="'+theImages[whichImage]+'">');
}

//  End -->
</script>

</HEAD>

<BODY>

</script>

This script is working very well on my webpage except that every time the image changes the screen flickers. Can you recommend a solution? Thank you!

love that this worked, but want the random image as the background. How do I specify that within the code?
