Very worth reading

Too short


It's a good start for building a page that passes image coordinates (in pixels) to some ASP page linked to it.
In facts the page linked to image should be prepared to receive two parameters (x,y).
To make this sample work just turn the provided javascript code into a function and then call it with onClick event when the user presses the mopuse button on the image, like in the code bekow here:
<script language="JavaScript">
function getxy() {
str = location.search;
if (str == "")
document.write("<p>No coordinates specified.");
else {
commaloc = str.indexOf(",");
document.write("<p>The x value is " + str.substring(1, commaloc));
document.write("<p>The y value is " + str.substring(commaloc+1, str.length));
<a href="#"><img src="/images/GNSoft_computer_works.gif" border="0" ismap onClick:getxy();></a>
