This is a Javascript topic, not MapServer. The brief explanation is --

The reason the browser sends the request on clicking on an image is
because that is what you are asking it to do. You are doing so by
possibly embedding the image in a form, or by trapping the mouseclick
and using Javascript to send back to the browser.

In your case, what you want to do is to modify that behavior. On
loading your map page, set up a Javascript array in which you collect
all the mouseclicks. As the user clicks around on the map, the map
coordinates are pushed into the Js array. Then, when the user is ready
the see the results of all that happy clicking, have her click on a
submit button, and send the Js array back to the server along with the
rest of the request.

Hope that is clear. When you implement that successfully, be sure to
share it with the rest of the list... someone else will benefit from
your effort.

Good luck.
