To add mapzoom just set the event onload="mapzoom.add(this);" to a div surrounded image.
To get individual area highlightings, add one or more classes to the image map area.
<map>
...
<area shape="poly" class="noborder vacolor00ff00" href="#" coords="...">
...
</map>
To get multiple area selections, add one or more id's to the areas rel attribute.
<map>
...
<area shape="poly" id="blue" rel="green,red" href="#" coords="...">
<area shape="poly" id="green" rel="red,blue" href="#" coords="...">
<area shape="poly" id="red" rel="green,blue" href="#" coords="...">
...
</map>
To force a group of areas using the attributes of the initial area.
<map>
...
<area shape="rect" id="black" class="forcegroup vacolor000000" rel="green,red,blue" href="#" coords="...">
...
</map>
To subtract one or more areas from another one, add the id's to the areas rev attribute.
<map>
...
<area shape="poly" id="red" rev="green,blue" href="#" coords="...">
<area shape="poly" id="blue" href="#" coords="...">
<area shape="poly" id="green" href="#" coords="...">
...
</map>
Add one or more classes to the image map area, to set individual preselection values.
<map>
...
<area shape="poly" class="specified pacolor00ff00 pbacolorfffff vaopacity50 vbopacity75" href="#" coords="...">

If you need utility functions, use "maputil.js". You can generate SVG files out of Image maps.
makeSVGfromMap(map, options);
<a href="#" onClick="makeSVGfromMap(document.getElementsByName("myimg")[0],false,502,482);">Generate SVG</a>
makeSVGfromMap()
parses the style attribute of <area /> tags for fill and stroke styles to complete the SVG!
scaleMapAreaCoords(map, nw, nh, sw, sh, options);
scaleMapAreaCoords()
opens a window with the source!
In very old browsers, the script degrades and your visitors won't notice a thing.

Please read the Frequently Asked Questions before you contact the author.
Element dimensions should always respect the Aspect Ratio of the image.
iOS (iPod/iPad/iPhone) Resource Limits (Quote):
"JPEG images can be up to 32 megapixels due to subsampling, which allows JPEG images to decode to a size that has one sixteenth the number of pixels. JPEG images larger than 2 megapixels are subsampled—that is, decoded to a reduced size. JPEG subsampling allows the user to view images from the latest digital cameras."
Android zooming (pinch gesture). Currently not, because android emulator do not support multiple finger gestures!
Internet Explorer's image scaling through bicubic interpolation is only available in version 7 and up. So don't expect to much (smooth display) from older browsers like IE 5, IE 5.5, and IE 6. IE needs external cursor images (*.cur). IE 6/7/8 do neither support vector borders nor vector fading.
Opera and old Safaris are unable to interpret style sheet percentages properly and exactly.
Handling javascript mouse events is not a simple thing, because there are inconsistancies in the way different browsers implement mouse events. That's the reason why the response on right mouse button is inconsistent in mapzoom. With Opera it's impossible to prevent the context menu from showing up.
