I have a 2021 iPad Pro. I have an SSD with images. How can I use the Photos app to view these images? I can see them in the Files app, but I can’t do things like play a slideshow from the Files app. I want to be able to run a slideshow of the images on an external drive. Is there another app that allows the user to see the external drive or is the Files app the only one? Thx!
