Question marked as
Photos must download the full sized version of any photo it is using in a slideshow. It appears that you have "Optimize Mac Storage" enabled on your Mac. (What type and model of Mac are you using and what system version are you running?)
So if you try to make a slideshow of all of your photos they must be downloaded to your Mac before you can create the slideshow or use the photo outside of the library, i.e. printing, emailing, etc.
Will you have enough room on your Mac to house all of the full sized image files in the library?
