Hi roninrr2
What I suggest you do is upload them in sets over a period of time. Thats a lot of images and its likely a one time upload might fail.
Also, I would not upload them through http://www.onedrive.com
Browsers crash and it makes it difficult to pick up from where you left off.
What you should do instead is drag and drop 5 GBs into the OneDrive folder in File Explorer, let it upload each set.
After you have successfully moved over each, you can enable OneDrive on demand, so you access only the photos you want when you need them.
