      var src = $(this).attr("src");
      var date = new Date();

      loaded =0;
    }
  });
  retries +=1;
  if(retries < 10){ //if after 10 retries error images are not fixed maybe because they are not present on server, the recursion will break the loop
    if(loaded == 0)
      {setTimeout('$.imgReload()',4000); // I think 4 seconds is enough to load a small image (<50k) from a slow server
    }
    //all images have been loaded
    else {// alert("images loaded");
    }
  }
  //if error images cannot be loaded  after 10 retries
  else {// alert("recursion exceeded");
  }
}
