Webcontainer embedded Dialog Order problem

Hi,
I have a Webdialog with an Imageview.
On mouse down over the image, I want to embedded a WebContainer over the image view at the specific location, but the embedded item is under, hidden by the image.
Is there a way to bring it front?
I want to do it that way, because I want to be be able to clic that container later instead of the image view at back.
thx
