Image Preload

[FaoX]

Ok so Im using image mapping for my link bar, but the problem is when I use my onlick action to show a diferent image it has to load it, and so for the first time you click it you may never see the click image. Is there a php or html way to preload those images when the page firsts loads so when the user clicks on the link it will already be downloaded and show the image?

simply preload the whole mouse-over script:
