First step - I am appending number of   <img>  tag in to specific div [Adding depends window width] see code here
function imgAdding() {
  for (var i = 0; i < ($(window).width()/100) -1  ; i++) {
    var $wrap = $('<img src="" width="100px" alt="" />');
    $('.img-wrap').append($wrap);
  }
}
Second step- Then adding different src path on each img tag [ ex: pic-1.gif , pic-2.gif , pic-3.gif  ]
//img name adding
function hexImgName () { 
   var count = 0;
   $("img").each(function(i) {
      var imgSRC = 'img/hex/pic-'+(count)+'.gif'
      $(this).attr('src',imgSRC );
      count = parseInt  (count) + 1 
   });
}
Working fine last two steps
my problem here 
Third step -I have only ten images in my img folder [pic-1.gif , pic-2.gif , .... last pic pic-10.gif ] , If there 15 img tag in html so last 5 img src path should fail -
my question
How can i find failed Image Error path via jQuery ? How can i randomly assign different src paths to our error images ?
