Look at the PHP FAQ, it's a great place to start:

7.13. I'm trying to use an <input type="image"> tag, but the $foo.x and
$foo.y variables aren't available. Where are they?
When submitting a form, it is possible to use an image instead of the
standard submit button with a tag like:
<input type="image" SRC="image.gif" NAME="foo">
When the user clicks somewhere on the image, the accompanying form will be
transmitted to the server with two additional variables: foo.x and foo.y.
Because $foo.x and $foo.y are invalid variable names in PHP, they are
automagically converted to $foo_x and $foo_y. That is, the periods are
replaced with underscores.

So basically, instead of checking for $submit, do something like:
... if (isset($submit_x)) { ...
