Hello Everybody, I'm a web designer from chicago. I'm working on some javascript code. It's jquery for a custom photo rotater that I created. It works right now but I'm looking to optimize it.

What do you guys think? Anything I can do to clean it up?

// JavaScript Document

//global parameters for controlling the sliding.

function slider(numpics, imgwidth, mydiv){
this.mypos = mydiv;
this.newpos = 0;
this.imgwidth = 0;
this.myarray = new Array;
this.mycounter = 0;
this.total = 0;
this.curpos = 0;
this.times;

this.intialize = intialize;
this.moveNext = moveNext;
this.movePrev = movePrev;
}

/*this function intializes the postions for sliding.  It has to be called on the page to make the sliding work.
numpics = number of divisons to slide through, 
imgwidth =  the width of the container,
mydiv = name of div that slides
*/
function intialize(numpics, imgwidth, mydiv){
while(this.mycounter < numpics){
  this.myarray[this.mycounter] = (imgwidth*this.mycounter)*-1;
  this.mycounter ++;
} 
this.total = numpics - 1;
this.mypos = mydiv;

  }

/*this function controls forward sliding*/
function moveNext(){
  if(this.newpos < this.total)
{this.newpos += 1;}
else
{this.newpos =0;  }
  this.curpos = this.myarray[this.newpos];
$(this.mypos).stop().animate({
    left:this.curpos
    }, 800, function (){});

}

/*this function controls backward sliding*/
function movePrev(){
  if(this.newpos > 0)
{this.newpos -= 1;}
else
{this.newpos = this.total;  }
  this.curpos = this.myarray[this.newpos];
$(this.mypos).stop().animate({
    left:this.curpos
    }, 800, function (){});
}
