    h=formatTwoDigits(h);
    m=formatTwoDigits(m);

window.onload=showDateTime;
function formatTwoDigits(s){
    if(s<10){
        return "0"+s;
    }
    else{
        return s;
    }
}
function imageDigits(s){
    var ret="";
    var s=new String(s);
    for (var i=0;i<s.length;i++){
        ret+='<img src="images/'+s.charAt(i)+'.png">';
    }
    return ret;
}

Answer 1

 ret+='<img src="images/'+s.charAt(i)+'.png">';
