I'm a new iCloud user and have a question. I just uploaded around 4000 photos to the cloud to free up storage space on my MacBook Pro. Before I delete the photos from my MacBook I want to make sure they're safe in the cloud and that apple won't delete them for any reason. I've paid for the 50G of extra storage and don't plan on uploading many more photos. Will my photos be safe in the cloud? Thank you!!!!
