I am searching for a good web based site for storage of all of my photo images in all forms of raw, tiff, and jpeg. The site needs to have security for a photographer, the ability to share photos as in a Yahoo Flickr album, and the capability to arrange thousands of photos in a library, as well as the capability to auto load all photos from my PC. I currently use Lightroom 6 to manage the photos on my PC. I do not know if Adobe has this capability yet?
Since you have the standalone version of Lightroom, you do not have the online creative cloud stuff but that comes with an amount of online storage that you can use for anything including photos (20GB if you have the full plan). It's not an awful lot of storage though. For what you want, I would look into any of the online data services such as Amazon cloud drive, dropbox, microsoft onedrive and many others. Most do all that you want, except for the flickr thing. Nothing that I know off does that automatically.
