Google photos tags my images and I don't have to worry about uploading myself.

Why would I use this?

The ability to earn via affiliates, add more detail and more... Worth looking at rather than just concluding?

Have you heard of FB/IG?

So not really worth considering, image sharing requires network effect, and that exists already. Why go where no one is? Who am I going to share with? Why am I hanging out in a ghost town?
