Capture Image and Set It to Image Control In GridView using JQuery.

Capture Image and Set It to Image Control In GridView using JQuery.

I am working on a webform.It contains a gridview.Each gridview has a linkbutton and image control.If i click on linkbutton,modelpopupextender shows up to capture an image through webcam.
I want to set the captured image to the selected row's image control.
I'm using following JQuery code but it applies to all the image controls in the gridview.

  1. <script type="text/javascript">
            var pageUrl = '<%=ResolveUrl("~/CS.aspx") %>';
            $(function () {
                jQuery("#webcam").webcam({
                    width: 320,
                    height: 240,
                    mode: "save",
                    swffile: '<%=ResolveUrl("~/Webcam_Plugin/jscam.swf") %>',
                    debug: function (type, status) {
                        $('#camStatus').append(type + ": " + status + '<br /><br />');
                    },
                    onSave: function (data) {
                        $.ajax({
                            type: "POST",
                            url: pageUrl + "/GetCapturedImage",
                            data: '',
                            contentType: "application/json; charset=utf-8",
                            dataType: "json",
                            success: function (r) {
                                $("[id*=imgOldEmployee]").css("visibility", "visible");
                                $("[id*=imgOldEmployee]").attr("src", r.d);
                            },
                            failure: function (response) {
                                alert(response.d);
                            }
                        });
                    },
                    onCapture: function () {
                        webcam.save(pageUrl);
                    }
                });
            });
        </script>
