I have to add one back button and one next button to my image viewer (built with arrays). what script should I apply to these buttons? what line of script should i add to my main code. Please help.

this.onLoad = function(){  
mypictures = [“tibet.jpg”, “tibet2.jpg”, “forest.jpg”, “einstein.jpg”, “bear.jpg”, “dragon.jpg”, “af1.jpg”, “ceppu.jpg”]  
numPics = mypictures.length;  
randomNum = Math.random(numPics);  
trace(randomNum);  
randomNum = randomNum \* numPics;  
trace(randomNum);  
randomNum = int(randomNum);  
trace(randomNum);  
thisTime = mypictures[randomNum];  
trace(thisTime);  
this.createEmptyMovieClip(“imageHolder\_mc”, 1);  
imageHolder\_mc.loadMovie(thisTime);  
this.imageHolder\_mc.\_xscale = 60;  
this.imageHolder\_mc.\_yscale = 60;  
this.\_x = 50; this.\_y = 40;  
\_root.photo\_name.text = thisTime;
