Add Cardtype support for ImageMaps including a Javascript map editor to edit ImageMap cards.  ImageMap+*image+*type_plus_right could be the image being mapped.  The content of the card would just be html fragments (<map> and sub-elements).

We probably want to put the deeper design solutions for rich intereaction with the mapped items to another idea card, but the simplest case should be able to map an array (Pointer or Seach results) onto a sequence of map areas, and maybe give some mouse-over and pop-out views from the refereced cards.
