hello everyone

I've used mwinter's excellant randomizing unit on more than several scripts to randomize their arrays, either onload or each time an image is requested by the script. Keep in mind that random means random and can look ordered at times. If something else is at work here, we need to see your code to figure out the problem. Just to be clear, it is post number 6 from the above thread mentioned by Mike that contains the fully formed randomizing unit and it must be used as he describes in that post.

PLEASE: Include the URL to your problematic webpage that you want help with.

Replace:

var randomizeimage="yes" //randomize dislay order of images? "yes" or "no"

function shuffleit(){ 
return Math.floor((Math.random()*fadeimages.length-1)) 
}

if (randomizeimage=="yes")
fadeimages.sort(shuffleit)

with:

var randomizeimage="yes" //randomize display order of images? "yes" or "no"

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;
};

if (randomizeimage=="yes")
fadeimages.shuffle()
