Question

I’ve some images on a page which are loaded randomly and they are over 100kbs, is it possible to have it fully loaded then fade it in rather than progressively loading it?

My JS looks like this…

(function($){   
$.randomImage = {
    defaults: {         
        //you can change these defaults to your own preferences.
        path: '_images/', //change this to the path of your images
        myImages: ['hero_eagle.jpg', 'hero_giraffe.jpg', 'hero_owl.jpg', 'hero_rabbit.jpg']
    }           
}   
$.fn.extend({
        randomImage:function(config) {              
            var config = $.extend({}, $.randomImage.defaults, config);              
             return this.each(function() {                      
                    var imageNames = config.myImages;                       
                    //get size of array, randomize a number from this
                    // use this number as the array index
                    var imageNamesSize = imageNames.length;
                    var lotteryNumber = Math.floor(Math.random()*imageNamesSize);
                    var winnerImage = imageNames[lotteryNumber];
                    var fullPath = config.path + winnerImage;                       

                    //put this image into DOM at class of randomImage
                    // alt tag will be image filename.
                    $(this).attr( { src: fullPath });                                   
            }); 
        }           
}); 

})(jQuery);

Should be able to, just set the image to display:none in your stylesheet and modify the bit of the script that sets the src to this:

$(this).attr( { src: fullPath }).load(function() {
  $(this).fadeIn()
});
