Preloading images with jQuery

I'm looking for a quick and easy way to preload images with JavaScript. I'm using jQuery if that's important.
I saw this here (http://nettuts.com...):

我再找快速方便的方式來預載圖片,我主要是用jQuery如果這重要的話

function complexLoad(config, fileNames) {
  for (var x = 0; x < fileNames.length; x++) {
    $("<img>").attr({
      id: fileNames[x],
      src: config.imgDir + fileNames[x] + config.imgFormat,
      title: "The " + fileNames[x] + " nebula"
    }).appendTo("#" + config.imgContainer).css({ display: "none" });
  }
};

But, it looks a bit over-the-top for what I want!
I know there are jQuery plugins out there that do this but they all seem a bit big (in size); I just need a quick, easy and short way of preloading images!

但是這個感覺有點太過頭太多了一點,
我知道有一些jQuery插件可以做得到,但是他們都感覺有點太大,我想找更快速簡潔的方式

Quick and easy:

快速簡潔:

function preload(arrayOfImages) {
    $(arrayOfImages).each(function(){
        $('<img/>')[0].src = this;
        // Alternatively you could use:
        // (new Image()).src = this;
    });
}
// Usage:

preload([
    'img/imageName.jpg',
    'img/anotherOne.jpg',
    'img/blahblahblah.jpg'
]);

Or, if you want a jQuery plugin:

如果你享用jQuery插件的話:

$.fn.preload = function() {
    this.each(function(){
        $('<img/>')[0].src = this;
    });
}

// Usage:

$(['img1.jpg','img2.jpg','img3.jpg']).preload();
