Move Photos from Dropbox to iCloud
So I have been using Dropbox to store all my picture and videos. I want to just use iCloud now. So in photos app I went to File -> Import and selected a few. I noticed this import folder that gets created. I do not want that folder. If I delete it, it deletes the photos. What is the best way to bring in my 5GB of photos and videos?
