Answer 1

You can trigger the form submit on the click of the images. This will work with the preventDefault().

var vote;
$(".vote_up, .vote_down").click(function(event) {
    vote = $(this).attr("class");
    $(".vote_form").trigger("submit");
});

$(".vote_form").submit(function(event) { 
    $form = $(this);
    $.post($form.attr("action"), $form.serialize() + "&submit="+ vote, function(data) {
        // do something with response (data)
    });     
    event.preventDefault();
});
