multiple jquery dialogs on the same page?

Here is my working java script for a single JQuery dialog button:

 $.fx.speeds._default = 800;
    $(function  thedialog() {
        $("#myDialog").dialog({

            autoOpen: false,
            show: 'slide',
            hide: 'explode',
            modal: false,
            width: 300,
            minHeight: 200,
            maxHeight: 500,
            buttons: {
                "Close": function () {
                    $(this).dialog("close");
                }
            }
        });

        $("#opener").click(function (e) {
            e.preventDefault();
            $("#myDialog").dialog("open").effect("highlight", {}, 2000);
            ;
            return false;
        });

        function positionDialog() {
            linkOffset = $("#opener").position();
            linkWidth = $("#opener").width();
            linkHeight = $("#opener").height();
            scrolltop = $(window).scrollTop();
            $("#myDialog").dialog("option", "position", [(linkOffset.left - 200 / 2) + linkWidth / 2, linkOffset.top + linkHeight - scrolltop]);
        }

        positionDialog();

        $(window).resize(function () {
            positionDialog();
        });

        $(window).scroll(function () {
            positionDialog();
        });
    });
</script>

Select allOpen in new window

In my HTML I use this:
<div id="myDialog" title="Dialog1">
<p>hello world</p>
  </div>
                <input type="image" name="opener" id="opener"  onmouseover="mouseOver()" onmouseout="mouseOut()" src="images/learnmore.png" onclick="return false;" />

Now I want to make another button (up to 10 more), but using the same ID for a button does not work.  If I change my second Button ID, then my script doesn't work.  If I use class="opener" for a second button, that doesn't work.  

 Any ideas on how to get multiple dialog's working on the same page, using image buttons?
