hi, I'm new here, and I can't get my conveyor belt slideshow randomized. I searched the forum and the solutions did not work for me. So here is my code (the standard code from dynamicdrive.com), hope anybody can adapt it for me!!!!

Put this:

//Randomizing Unit Courtesy of Mike Winter as seen at:
//http://www.dynamicdrive.com/forums/showthread.php?p=8442
function random(n) {
  return Math.floor((Math.random() % 1) * n);
}

Array.prototype.shuffle = function() {var i = this.length;
  while(i--) {this.swap(i, random(i + 1));}
};
Array.prototype.swap = function(x, y) {
  var t = this[x]; this[x] = this[y]; this[y] = t;
};

leftrightslide.shuffle()
//End Randomizing Unit

many thanks!!

just one more question, what do I have to do to make every picture, when clicked on, be opened in a new window?

[jscheuer1]

Not sure what you are asking. Do you want each picture when clicked to open a new window that contains the picture just clicked on or to open a new window with some other content in it? In the first case copy this template for each image:

leftrightslide[0]='<a href="img/2alonso03_thumb.jpg" target="_blank"><img src="img/2alonso03_thumb.jpg" border=1></a>'

In the second case use this template:

leftrightslide[0]='<a href="page.htm" target="_blank"><img src="img/2alonso03_thumb.jpg" border=1></a>'

where page.htm is the path and filename of the content you want in the new window. You can use an image instead if you want to.
