Fscommand to trigger lightbox

I`m using a javascript library called slimbox that makes images pop up in a window type thing.

I would like to execute this from flash but don’t have a clue how to do it. In html the code that opens the window is

<a href="R-interior.jpg" rel="lightbox" title="test">Rublevo Exterior Patio</a>

its the rel=“lightbox” that triggers the javascript, anyone know how I can trigger it from flash?

many thanks
