I’ve created a gallery using a portfolio option with featured images of each portfolio entry as images in gallery. I want to change one thing – currently all links use lightbox but each link generates new “Gallery” in lightbox, so I can’t toggle between images on the same site when they are enchanced in lightbox. How can I change that? I want them all on this page to be in one gallery in lightbox but I have no idea how to change rel=”” attribute for those links. In which file are they generated?
