Tutorial Image Preloader
Very easy way to preload images which are needed later (e.g. when a hover is performed)
<script type="text/javascript">
$.preloadImages = function()
{
for(var i = 0; i<arguments.length; i++)
{
$("<img />").attr("src", arguments[i]);
}
}
$(document).ready(function()
{
$.preloadImages("hoverimage1.jpg","hoverimage2.jpg");
});
</script>
