Hello,

Is there a way to assign linked href values to an image map object after 
the object has already loaded?

For example, if the page loads first including a usemap object: 
<img src="mymap.jpg" usemap="#mymap" id="hello">
(without any href values).

Thereafter, and once the page has already loaded, assign by a JS function 
its href dom values, as if the following becomes present in the html:
<map name="mymap">
<area shape="rect" coords="20,20,60,220" href="rect.html">
</map>

Or, initially load the image as a normal image (<img src="mymap.jpg" 
id="hello">) and thereafter make it a usemap="#.. and add the linked 
coordinates.

Can this be done? If so, what is the most direct way?

Many thanks,
Tuxedo
