I thought some folks would be interested in this. I have gone through and uploaded all of the pictures I have taken over the last five years to iCloud Photo Library using the beta website. I uploaded 10,598 pictures. These pictures have now synched back down to my iPhone 6 and my iPad mini 2, so what is stored on the IOS devices should all be optimized copies of the pictures. On my iPhone 6 the pictures are taking up 7GB and on my iPad 7.2GB. Now one problem I have run into is the older the pictures were, the more likely they might not contain good dates or location information, so Moments get messed up and as far as I can tell there is no way to fix this. I have pictures taken 5 years ago appearing as if taken today. Maybe the Mac Photos app will have some way to move these Moments around. Anyway I thought some folks who are considering uploading pictures to IPL might be interested in these numbers.
