Create or rename an album to "Veezy" (without quotes). Open the app. Rejoice.
That won't work.
Yes. We recommend that, so you can have family or friends add photos to your "photo frame".
Random every time it starts over looping the album (the app doesn't have to be closed and re-opened).
For Veezy to be super memory-efficient (less than 16MB RAM while running on slideshow, booyah!), it uses photos cache. If you never opened your photos album or you just restarted your iPad, there will be nothing. Play a Photos slideshow once with your album, and you'll be good to go.
