To have a popup box when mouse hovers, use the “title” attribute in your link: <a href="somelink" title="this is some nice link">somelink</a>. Example: hover me and don't move you mouse for a second
If you want to control the size and color of the popup box, or placing links and images in it, use Erik Bosrup's overlib at: http://www.bosrup.com/web/overlib/ Example: Please mouse over me.
