Hi @EmilyGeo currently when you add related records (multiple photos from 123 in this case) to a pop-up you have to click on Attach photo and then see the photos.
I think it might to have an option to directly see the photos under the main pop-up (and also maybe have some layout options as well to like see all the pics in a gallery layout or show one pic at a time with right and left arrows to go the next pic) rather than having to click on Attach photo
