Javascript links

I want to display some small films from another site. They gave me authorization to do this, but they send the file address inside a CGI code, that looks more or less like this:

<a onclick="javascript:window.open('http://www.thevideos.com/pop_160.asp?COD=10&Exib=4307','','width=560,height=525,top=0,scrollbars=YES')" href="#">  Text or image here </a>

How could I make this work nicely inside the gallery?
Thanks!
