jQuery, JavaScript, HTML: how to load images after everything else is loaded?

Here’s what we did and its working great. We skipped setting src attribute of img and added img-location to a fake attribute lsrc. Then we load a dynamic image with lsrc value, and set the src of actual image only after its loaded.

Its not about faster loading, but its about showing the images only when its downloaded completely on your page, so that user do not have to see that annoying half-loaded images. A placeholder-image can be used while the actual images are being loaded.

Here’s the code.

 $(function(){
    $.each(document.images, function(){
               var this_image = this;
               var src = $(this_image).attr('src') || '' ;
               if(!src.length > 0){
                   //this_image.src = options.loading; // show loading
                   var lsrc = $(this_image).attr('lsrc') || '' ;
                   if(lsrc.length > 0){
                       var img = new Image();
                       img.src = lsrc;
                       $(img).load(function() {
                           this_image.src = this.src;
                       });
                   }
               }
           });
  });

Edit: Trick is to set the src attribute only when that source is loaded in temporary img. $(img).load(fn); handles that.
