for running the lightbox in jquery you must click on one image('a' link) of the gallery then immediately lightbox runs....
$('#gallery a').lightBox();
but i am going to use the lightbox as a zoom, that means i have a button 'ZOOM', by clicking this buttom i am going to open my gallery...
i don't know how i can do this...
you could use:
$('#gallery a').lightBox();
$('#zoomButton').click(function(){
$('#gallery a:first').click();
})
Or possibly
$('#gallery a:first').trigger();
Untested but should work
