This web page shows an example of an image map with a rollover effect. Some of the faces shown below have active regions associated with them and if you move your mouse into these regions the entire image is automatically swapped for a new image highlighting the face that is being hovered over. A text box is also shown giving information about the highlighted area. Some of the faces have hyperlinks associated with them; in these cases clicking on a face will cause the browser to jump to a new web page.
This is an example of one of the replacement images that is shown when one of the faces is hovered over.
This is the transparent window with a black surround that can be used as a starting point for generating a rollover overlay for your own photographs.
