Move photos from iMac to iCloud I have thousands of photos on my iMac and want to save them to iCloud.

How can I save my photos to iCloud, and how can I find them again?
If you have OS X Yosemite (10.10), you can use iCloud Drive to store your photos, as you're only limited to the amount of storage space you have available under your iCloud account. Apple details how you can store documents onto your iCloud Drive here
