Hi meinhardg,
Welcome to the Roku Community!
Thank you for letting us know that you are unable to view your desired photos in the photo stream on your Roku. No worries, I'm more than happy to provide you with more information about this.
You can upload up to 100 photos to each stream in JPG, PNG, HEIC, and WEBP formats. However, a stream may not allow 100 photos if the storage limit for the Roku account has been exceeded.
How to view a slideshow on your TV:
- Press Home on your Roku remote
- Use the directional pad to move to the right and highlight the Photo Streams channel. The directional pad is plus-shaped and is in the center of your Roku remote.
- Press OK to launch the channel
- Each row is an individual Photo Stream. Move down the screen and find the stream you want to view.
- Select a photo to see it larger
- Select Slideshow to see all images in the stream
During a slideshow, each photo appears for 10 seconds and the stream loops in a random order.
For reference, you can visit this support article: How to use Photo Streams on your Roku streaming device
Please let us know if these troubleshooting steps help you.
Regards,
Riamie
