Function to preload images?

Question

I\'m successfully pre-loading an image on my website with this JavaScript:

loveHover = new Image();
loveHover.src = \"http://mypage.com/images/love-hover.png\";

Well the unique part of the function would be the src (link to image). So make that the argument.

function preloadImage(src) {
    var image = new Image();
    image.src = src;
}

Then if you have multiple urls store them in an array:

var imageSrcs = [
    "http://mypage.com/images/love-hover.png#",
    "http://mypage.com/images/love-hover2.png",
    "http://mypage.com/images/love-hover3.png"
];

And preload the images with a loop:

for (var i = 0; i < imageSrcs.lengthl i++)
    preloadImage(imageSrcs[i]);
