The script imagemap.phpΔ adds markup to define image maps from within the wiki page.

Download imagemap.phpΔ and copy to the cookbook directory, install by adding to config.php:



%usemap=#mapname%Attach:image.jpg- loads image.jpg and associates an image map mapname with it.
 - The hash # in front of the name is required
(:imgmap mapname:)- opening markup with name of map serving as anchor
(:area href= shape= coords= :)- various area markups defining clickable areas within the image, repeat as required
(:imgmapend:)- closing markup

It does not matter where on the page the imgmap markup is written, it does not produce any output by itself, only via the associated image.

Each (:area .... :) markup includes a number of parameters:

  • href=`Group.PageName or
  • href= defines the link associated with the area of the image.
  • shape= defines the shape of the area.
    • shape=rect for a rectangle
    • shape=circle
    • shape=polygon
    • shape=default without coords associates the whole image.
  • coords= defines the areas coordinates as a string of numbers separated by commas, in pixels.
    • for a rectangle: coords=x1,y1,x2,y2 (topleft corner 1, bottom right corner 2, measured from left image border distance x and from top image border distance y)
    • for a circle: coords=x,y,r (left to centre, top to centre, circle radius)
    • for a polygon: coords=x1,y1,x2,y2,x3,y3,x4,y4,x5,y5,... (corners of polygon, each corner measured frm left as x and from top as y)

Further optional parameters:

  • title=' title name ' (shows as tooltip when moused over) Make sure that several words are enclosed in single quote marks '...'
  • alt='alternative text' (for browsers with no image support)
  • tabindex=number (to aid tab navigation)
  • accesskey='key' (to aid keyboard navigation)
  • onclick='javascript commands' (needs $EnableOnclickJavascripting turned on, default is off)

If any areas defined overlap each other then the area on top should come before the area underneath. If the image as a whole is defined as default area with shape=default it should come last, just before the (:imgmapend:) markup.


%usemap=#testmap center%Attach:imagemap-sample.jpg
(:imgmap testmap:)
(:area shape=rect coords=10,83,118,227 href=PmWiki.Documentation title='Red rectangle: Documentation' :)
(:area shape=polygon coords=157,10,215,10,245,60,215,110,155,110,125,60 href=Cookbook/ title='Yellow hexagon: Cookbook' :)
(:area shape=circle coords=110,80,60 href="" title='Green circle: Google' :)
(:area shape=polygon coords=155,140,240,140,240,215,215,215,215,155,155,155 href=Cookbook.Skins title='Blue shape: Skins' :)
(:area shape=default href=Main.HomePage title='Default area: HomePage' :)


Avoid paragraphs in the list of imagemap areas: Using paragraph markup (two linebreaks in succession = an empty line) causes the HTML output of the script to be non-conformal with XHML 1.0 and might cause the map to work improperly in some browsers.

Conflict with LineBreaks: If you configured your wiki to honour line breaks (new lines) then you need to put before the (:imgmap:) markup (:nolinebreaks:) and after (:imgmapend:) put (:linebreaks:).

Show image at original size: Don't use the width= or other scaling of the original image
