Image prefetch with javascript

In order to Perform image prefetching with javascript we need to create an Image object and insert an url in ITS 'src' global variable, AS FOLLOWS:

var img = new Image ()
img.src = ' http://my_url.jpg '

Then we can attach handlers in order to be Advised When fetching operation completes Or When it goes wrong:

img.onload = function () {
/ / remove placeholder image and show
}

img.onerror = function () {
/ / remove placeholder That image loading and print Went Wrong
}

That's all, enjoy
