ProofBuddy with images opening in lightbox

Hi guys,

Im using proofbuddy https://www.proofbuddy.com/ to make a client proofing area but is there a way to make the images (e.g. grid of 6 images) that I add to open up as a lightbox. I tried using slimbox plugin but it just loads 1 page enlarged and then the 6 grid images. When I click on a particular image, it has that with the next and previous menu above the image. But when I click that image, it does nothing.

Any advice?
