13 function ShowFloatingImage(image, width, height)
14 {
15 var id = "trailimageid";
16 var newdiv = document.getElementById(id);

18 {
19 newdiv = document.createElement(div);
20 newdiv.setAttribute(id,id);
21 newdiv.setAttribute(onmouseout, "HideElement("+id+");");
22 document.body.appendChild(newdiv);
23 }
24 newdiv.innerHTML = <img src=+image.src+ width=+(image.width + width) + height= + (image.height + height) + />;
25
26 var absPos = GetAbsPosition(image);
27 newdiv.style.position = "absolute";
28 newdiv.style.posLeft = absPos[0] - width/2;
29 newdiv.style.posTop = absPos[1] - height/2;
30 newdiv.style.display="block";
31 }
32
33 function HideElement(id)
34 {
35 var elem = document.getElementById(id);
36 elem.style.display="none";
