i'm trying to make a rollover menu on the side of my page. But the page won't show the images...at all! even when I put in just the images without them being buttons, they simply don't show up. The links to the images are correct, the div is present and in place and I can even write some text in it. But it just WILL NOT display images it seems.
It is all visible at http://www.sjoerdoudman.nl/wordpress. The Div in question is the one colored yellow.
is there a good explanation for all of this?
