the src attribute on the img factor specifies the
image "pages.gif". the usemap attribute
references a map factor. it uses a web address to do so,
Windows 7, hence
the # character. the border attribute is set to
"0" to suppress the blue border around the picture.
the map aspect specifies which regions in the picture act as
hypertext links. the name attribute matches usemap
attribute about the img factor and acts much like the name
attribute about the <a> aspect. in practice,
Windows 7 Pro, the map element
needs to be in the same file as the img aspect.
the area aspect is used to define a region about the image and
to bind it to a web address. the shape attribute specifies
"rect",
Office 2010 Professional, "circle" or "poly". the coords attribute specifies the coordinates for the region
depending within the shape.
