Syntax

  • <img usemap="#[map-name]">
  • <map name="[map-name]"></map>
  • <area>

Parameters

Tag/AttributeValue
<img>Below are the image map-specific attributes to use with <img>. Regular <img> attributes apply.
usemapThe name of the map with a hash symbol prepended to it. For example, for a map with name="map", the image should have usemap="#map".
  
<map> 
nameThe name of the map to identify it. To be used with the image's usemap attribute.
  
<area>Below are <area>-specific attributes. When href is specified, making the <area> a link, <area> also supports all of the attributes of the anchor tag (<a>) except ping. See them at the MDN docs.
altThe alternate text to display if images are not supported. This is only necessary if href is also set on the <area>.
coordsThe coordinates outlining the selectable area. When shape="polygon", this should be set to a list of "x, y" pairs separated by commas (i.e., shape="polygon" coords="x1, y1, x2, y2, x3, y3, ..."). When shape="rectangle", this should be set to left, top, right, bottom. When shape="circle", this should be set to centerX, centerY, radius.
hrefThe URL of the hyperlink, if specified. If it is omitted, then the <area> will not represent a hyperlink.
shapeThe shape of the <area>. Can be set to default to select the entire image (no coords attribute necessary), circle or circ for a circle, rectangle or rect for a rectangle, and polygon or poly for a polygonal area specified by corner points.

Remarks

  • The above parameters list is modified from the MDN docs: <map> and <area>.

  • It is feasible to create an image map's coordinates with for an image with simpler shapes (such as in the introductory example above) with an image editor that shows coordinates (such as GIMP). However, it might be easier in general to use an image map generator, such as this one.
