Why isn't Photostream working on my desktop?

Episode 1058 (2:05:51)

Jim from Morrison, CO

Jim's having trouble with PhotoStream on his Desktop. It works fine on his mobile devices, though. Leo wonders if Jim turned it off on his Desktop by mistake. This is not unusual for Apple to have problems with their online service. He recommends enabling it through iCloud. He should also turn it off and turn it on again on all devices.
