As far as I know this is how submitting with images works:
<input name="something"> will send something.x and something.y to the
server. There _might_ be a 'pure' 'something', but as far as I know this is
optional/not strictly necessary, well I'm too laxy to read the
documentation, but at least it's not always sent, therefor unreliable.
In PHP, something.x and something.y will be transformed to something_x and
something_y to form valid keys for the POST array. These two values will
contain the coordinates clicked.
If you want another value then the clicked coordinates, you shouldn't use
type="image", but style an <input type=submit> or perhaps use a <button>
Grtz,
