Some Roku devices have a USB port to which a flash memory could be attached. If your device supports USB, you can add images to a USB flash memory and display them on your TV using PhotoTV. Supported image types are .jpg, .jpeg and .png. To set this up, you will need to do the 2 following steps:
1. Create a USB source.
2. Link folders under your USB source.
At any time, you can modify source and folder information, link more sources, folders, etc. Changes to the settings as well as folder content will be applied the next time the slideshow/screensaver runs.
