Hi Ellen ,
In this code, you are trying to run .show() function on a shown image. So, this statement wont work until you hide the image on load.
$w('#HudsonNewsLogo').show("zoom"), zoomOptions);
Regarding the zoomOptions, its a variable that you should declare, to specify the delay and duration of the zoom effect. For more information- Check THIS
Hope this helps!
Best,
Mustafa
