essayer cette façon :

var slideThumbCount = 3; // ??? 

$(document).ready(function() { 

    var theW = 249 * slideThumbCount, 
     bCountRef = $("div.bCont"), 
     slideThumbCountImage = 0, 
     onEndLoadImage = function() { 

     // check this 
     $(bCountRef).find("div.bsThumb").show(); 

     $(bCountRef).animate({left: 50}, 5000, function() { 
      alert('done'); 
     }); 

     }; 

    $(bCountRef).css("width", theW).css("left", "0px"); 

    for(i = 0; i <slideThumbCount; i++) { 

     $("<img />") 
      .attr("src", "imgDirectory/scrollingImages/img_" + i + ".png") 
      .load(function(ev){ 

       $('<div style="display:none">') 
       .attr("class","bsThumb bs_" + i) 
       .append(this) // <----- 
       .appendTo("div.bCont"); 

       // control for completion of the loading images 
       slideThumbCountImage++; 
       if (slideThumbCountImage == slideThumbCount) 
        onEndLoadImage(); 

      }); 
    } 

});
