I use iCloud Photo Library with Optimize Storage. When trying to run a presentation/slideshow, it takes a long time before each picture or video is presented in high resolution. I know this is due to my local connection quality, but can’t do anything about that. So I wonder whether it is possible to temporarily preload the images I want to present without having to save a duplicate/backup copy of them first. The reason is that I would like to interact with the originals (mark favorites, tag people etc) while running the slideshow. Also, if I want to present the images in Apple Photos from my duplicate backup, Photos will offer to re-import them, which is not what I want…
Thank you for any help,
Albrecht
