Answer 1

you may use onclick

<input type="image" onclick="sendme('<?php echo $href ?>')" src="<?php echo $image ?>">

and add this to your page :

<form method="post" id="myform">
<input type="hidden" name="submit_blue" id="submit_blue" value="" >
</form>
<script>
function sendme(x) {
    document.getElementById("submit_blue").value = x;
    document.getElementById("myform").submit();
}
</script>

that is a javascript solution i use if i do not want to use jquery or something

By the way I don't like using URL as a value
