On the right side, under the portrait of the two girls, you will see a list of four links next to some dates. onMouseOver, the photograph of the girls should change. This works fine in IE, Firefox, Safari and Opera.
In Chrome, however, it seems (using Chrome Developer Tools) that Chrome load the images each time, instead of preloading, and displaying the cached image each time i onMouseOver.
function change_image(img)
{
var h = document.getElementById('img_holder');
var imgs = h.getElementByTagName('img');
for(var i = 0; i < imgs.length; i++)
{
imgs[i].style.display = 'none';
}
document.getElementById(img).style.display = '';
}
