I am creating a (architectural) site that will have lots of various project pages, each displaying photography of the buildings we’ve designed. Different projects will have different numbers of photos that we wish to use; anything from two or three to about a dozen or so.
Is there a way I can set up a page so it automatically loads the relevant images, regardless of how many there are? It’s going to be a simple gridded layout of images (thumbnails to click on), I just am unsure how to go about this.
 Would setting up a separate collection to the “projects” collection I’ve already set up, titled say “project images” where each collection has multiple images that can be then referenced on a “project” page via a collection list be the way to go? Or would that result in me having to create a new collection per-project?
