    populate a div using array

    i've been trying to populate a div with multiple images with the help of an array.what could be the mistakes in here ?
    Code:
    <!doctype html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>Untitled Document</title>
    <style>
    *{
    	margin:0px;padding:0px;}
    
    #slider{
    	width:100%;
    	height:150px;
    	border:1px solid black;
    	position:absolute;
    	top:200px;
    }
    #slider img{
    	width:100px;
    	height:140px;
    	margin-left:2px;
    }
    </style>
    <script>
    function l(){
    var imag=["image1.jpg","image2.jpg","image3.jpg","image4.jpg"];
    var m=document.getElementById("slider");
     get_width=m.offsetWidth;
    var no_of_img=parseInt(get_width/(100));
    var i;
    for(i=0;i<no_of_img;i++){
    	m.appendChild += <img src="imag[i]" /> ;
    }
    
    }
    
    </script>
    
    
    
    </head>
    
    
    <body style="position:relative;">
    <div  id="board"></div><div id="imagebox"></div>
    <div id="slider"></div>

     for(i=0;i<no_of_img;i++){ // syntacx for mixing string with varioble
    	m.innerHTML += '<img src="'+imag[i%imag.length]+'" />'; // as no_of_img is geater than imag.length modulus(%) is used to repeat the images
     }
    
    }
