magnifier image over OSM map image

Hi all,
I use image magnifier to expand an image over Open Street Map, but when I press mouse button over the image to enlarge, it is enlarged under OSM map.
How can I enlarge above OSM?
Best regards,

Sergio

Solved.
for that who have my problem...
Loking over internet I have found this css workaround to set map zorder so down

Code:

---

html, body, #map {
        margin: 0;
        width: 100%;
        height: 100%;
}

#map {
    z-index: 1;
}

---

Now, when I magnify an image, it is displayed over map.
