class="alt"><img src="../images/up.gif" border="0" onclick="javascript:DisShowDataMain(this);" id="img4" />

function DisShowDataMain(imgObj) {

            var obj2 = document.getElementById("queryMain");

            if (obj2.style.display == "none") {

                obj2.style.display = "block";

                imgObj.src = "../images/up.gif";

            }

            else {

                obj2.style.display = "none";

                imgObj.src = "../images/down.gif";

            }

        }
