From your app menu, hover over the YoPhotos app, and click "App Settings."
On the right, select the number of photos you would like to include in the slideshow, then, using the form on the left, upload and name each photo.
Choose the theme for the album on the right. You can preview each one by selecting it, saving, and clicking the "Preview" button on the top right.
You can install YoPhotos as many times as you like, should you need multiple photo albums.
