But you cannot submit a form with a link unless you use javascript - which
is not a good idea if you want to make sure your forms always get submitted.
Instead, you need to use the image input tag and then on the server-side
check for its "existence" in the query parameters. You have got to do this
because it doesn't function like a normal button. Instead, when pressed the
coordinates of where you click on the image are sent as parameters, which
comes out to look like:
foo.jsp?imageField.x=13&imageField.y=12
You can't name these "image buttons", so if you have more than one they are
named in the order they appear in the html, so if the user clicked on the
third image button, it would look like this in the query string:
foo.jsp?imageField3.x=42&imageField3.y=16
This means you'll need to ensure that they always remain in the same order
in the html, or you'll need to change something in your code. IMHO, I don't
think this is worth the hassle and is error prone - use regular submit
buttons instead if possible.
