Assertion:
If an image is used as an image map in a document, the coordinates specified in the AREA elements must represent the coordinates on the image AS IT WILL BE USED in the document. Eg: if different HEIGHT and/or WIDTH attributes are specified in the IMG element the map coordinates must reflect this. Take care - if percentage heights and widths are specified, it will be almost IMPOSSIBLE to give accurate coordinates in the client side image map. This warning applies to all browsers surveyed that support client-side image maps.
