Drawing Image over another Image

Hello Everyone, I am completely new to isomorphic smartclient and need to write an application using isomorphic that shows the real image of the router with its cards, fans, powersupply and LED images on top of it.

Would like to know, if it is possible to draw an image over another image without creating a Pane.

For instance:

I have drawn one image using DrawImage on an existing Pane(lUserPanel_o) and it gets displayed properly.

lTopInd = isc.DrawImage.create({
src: null,
image: lTopImg,
left: 0,
top: 0,
width: 1208,
height: 810,
drawPane: lUserPanel_o
});

Now, can i draw another image over lTopEnd using below code(coz i read somewhere that isc image can be drawn over Pane only)?

lTopInd2 = isc.DrawImage.create({
src: null,
image: lTopImg2,
left: 100,
top: 100,
width: 1000,
height: 600,
drawPane: lTopInd
});

Note: lTopImg and lTopImg2 are valid non null Image components
