如何使Ajax调用的图像相互平滑转换？

我已经实现了从1000多个图像中获取单个图像的代码。但是Ajax调用改变了图像，导致每个映像的下载时间不同。该如何使图像相互平滑转换？即没有任何闪烁和Ajax处理图像。

You could pre-select the images you are about to load and store it in a persistent array:

var image_paths = new Array();
/* fill image_paths */

window.preload_images = new Array();

for (var i in image_paths) {
    var image_src = image_paths[i];
    var img = new Image();
    img.src = image_src;
    preload_images.push(img);
}

This will tell the DOM to load the image into a JavaScript Image object but to not destroy it unless preload_images is unset.
