We haven't been fully satisifed with some of the answers we've been giving regarding registration of photographs (we recently revised this one). So, we put together this video. We hope to follow up with a video on using the eCO filing system for similar purposes although eCO, as we've noted in the past, only works if the group of photos is unpublished or was published as a "single unit" of publication. Also, no releases were obtained for the "Picasa sequence" in the movie so please don't sue (you know who you are!).
