window.open - trying to display a new window with a different title - HELP

[linab2007]

I need to open a new window from an existing HTML page to a site in
which we do not want to show the address for. I have set the titlebar
to no but it will still place the title on the titlebar Here's my
function code:

function myOpen()
{
window.open("http://
www.somewhere.com","mywindow","location=no,titlebar=no");
}

I am calling it by the following line:

<img src="art.gif" onclick="myOpen()">

Any help you can provide would be extremely appreciated!!

thanks,
LB
