Hotspots with html form values

[davecousins]

Is there a javascript method for using hotspots that can output values to be read by a perlscript. I have achieved this using embedded radio buttons as layers over an image map, this seems a very clunky way of doing it. Also layers seem to have problems with varying screen resolution

I'm not sure if I understand your query correctly, but couldn't you just make the image map <area> hyperlinks point to a HTTP GET query, like this:

<area href="example.pl?variable=value">
