I have 60 GB of photos on an external hard disk.
I also have a MacBook Air with an empty iPhoto app. The MacBook has 15 gigs left of HD space.
Can I import these photos directly into the iCloud Photo Library?
I can only find articles which explain how to upload your complete library to iCloud, after which it starts optimising for storage. However I don't have enough space to fit all my photos on the internal hard disk.
