A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
It's possible the photos are still syncing with the cloud.
Also lightroom shares will not include PSB photos which is annoying....
Others have mentioned good cloud based solutions. I use both google drive and dropbox.
Clients seem to prefer dropbox.
