The OneDrive site won’t necessarily play them, but you can download. Applications like the Photos app in Windows 10 can then save frames as photos (Edit & Create->Save Photos). If you want to then upload the photos to Jet Photographic (https://jetphotographic.com/, Upload YOUR images here) and get mounted prints made up then that is absolutely fine by me.
