Don’t load hidden images
$(‘hiddenDiv’).addClassName(‘reveal’);Here is method 2:
Here’s a jQuery solution:
this.src = “”;
var reveal = function (selector)
var img = $(selector);
img.src = img.data(“src”);
});It’s similar to your solution, except it doesn’t use the fakeSrc attribute in the markup. It clears the src attribute to stop it from loading and stores it elsewhere. Once you are ready to show the image, you use the reveal function much like you do in your solution. I apologize if you do not use jQuery, but the process should be transferable to whichever framework (if any) that you use.
Note: This code specifically must be ran before the window has fired the load event but after the DOM has been loaded.
It partially depends on how your images must be placed in your code. Are you able to display the images as the background of a
If you don’t require the tag, most browsers won’t load images referenced by CSS until the element in question becomes visible.
Mind you that short of using AJAX to download the image there’s no way to be 100% sure the browser won’t pre-load the image anyway. It’s not unbelievable that a browser would want to pre-load anything it assumes may be used later in order to “speed up” the average load times.
Based on CD Sanchez solution, I made a small plugin:
$.fn.reveal = function(options)
var img = $(this),
src = img.data(“src”);
src && img.attr(“src”, src).show(options);
$(this).data(“src”, this.src).attr(“src”, “”);
})(jQuery);Just run .reveal on the image(s) you want to load. Check jsFiddle
Though, for perspective, most people have the opposite problem where they want to preload an image so it shows up instantly when it’s told to be shown.
