Can shared picture/video files be shared as thumbnails & streamable videos?

#1

Just a general question: I have been using Nextcloud as my Dropbox replacement for home movie storage and sharing with friends & family. One thing I really liked about Dropbox was that I can share a folder of videos and photos and they could see thumbnails, stream video, and download only what they wanted to. So far it looks like my Nextcloud share gives users the ability to download. Which is better than nothing, but I’d like to know if there’s an option or an extension I can set up to allow grandma to just view the videos without having to walk her through what “download” means and why she doesn’t need to download the same video 30 times.
