Smessed-Up

basically once one of the images is created randomly i want it removed from the array so it cant come up again but for some reason not all the images are appearing anyway heres what ive got whats wrong/missing?

[code]var image=new Array();
var g='.gif';
image[0]='image1'+g;
image[1]='image2'+g;
image[2]='image3'+g;
image[3]='image4'+g;
image[4]='image5'+g;
var l=image.length;
var buff=new Array();
for(i=0;i<l;i++){

buff[i]=new Image();
buff[i].src=image[i];

}

var randomNumber=Math.floor(Math.random()*l);
for(i=0;i<l;i++){

document.write('<img src="'+image[randomNumber]+'">');
image.splice(randomNumber,1);

}
