I've not written code to do it but that seems pretty simple to me. You
get the image from circle.php, detect where the circle is - pretty
simple - and pass those coords through when posting the form. Or have I
missed something?

Yup, it's as simpel like that, but I found an even simpler way,because
there is a bug in Tedd's code :P
You didn't check if the session variable is empty, so if i Pass an
empty variable Submit.x and Submit.y to your script, it generates 2
warnings, but tells me, Congratulations, you made it...
