I would like to know if anyone has a good workflow for transferring photos from Lightroom to the icloud photo library. My current Lightroom library is approximately 135Gb and is stored on an external hard drive as my MacBook Pro only has a 128Gb SSD. I would ultimately like to use my icloud photo library to backup and access all of my photos from any of my devices but have not been able to find a way to upload easily. I could import my Lightroom library into OSX photo with storage optimization turned on but I do not have the spare space to temporarily stored the photos on my MacBook Pro SSD while the upload. I have also read that if you have your OSX photo library stored on an external drive, the app will not sync your photos with your icloud photo library, does anyone know if you can manually sync the photos as long as you have your external hard drive plugged in. My only other option was to use my old laptop to upload images to the icloud photo library using the website. There must be an easier way of doing this, hopefully someone has a good work around..
