from Google Photos and seemingly my entire library uploaded properly (yay). However only a certain set of photos had their thumbnails generated and function properly. If I select a range of photos and force re-generate the thumbnails the images and videos all work properly.
But I have SO many photos that this will seemingly be impossible to do from the web interface, is there a command line utility that could either: - Re-generate thumbs for photos without thumbnails - Re-generate thumbs for the entire library
