Linking to multi-image from a single lightbox

Hi guys,

I am trying to make it so that when a div with a background image is clicked, it opens up a lightbox linked to the multi-image field. I know that I can drop in a dynamic gallery and add a lightbox there, but I don’t want to display the whole collection list on the page - I just want to display a single image and then display the gallery within the lightbox once the image is clicked. Is there an easy way to do this?
