How do I add additional images to an existing LR catalog? Ex. I have a catalog entitled Yosemite-2''9 with images in it. I take more images of Yosemite and want to add those to that catalog.
Robert's observations are correct. The simplest way is to open the catalog and in the Library module press the IMPORT button.
If, perhaps, you are talking about a Collection in an already existing catalog (a lot of people mix these up) then you can simply drag the images and drop them on the collection you want them in.
