var src = document.getElementById("x");

document.getElementById("showImage").onclick = function() {
    document.getElementById("theImage").style.visibility = "visible";
}

#theImage { visibility: hidden; }

function setImageVisible(id, visible) {
    var img = document.getElementById(id);
    img.style.visibility = (visible ? 'visible' : 'hidden');
