Viewing/Downloading pictures from iCloud

I'm having a big problem trying to download my iCloud pics on my PC. They are all there in the album, but as I'm scrolling up and down I see only the same single page of pics until I hover over each photo. When I attempt to select pics to download, and I scroll down, no pics show up at all so I can't see what I want to select. Very frustrating, any help is appreciated. Thanks!
