Looking for a digital Wi-Fi photo frame?

Hello, I'm looking for a digital photo frame.

Requirements:

• At least 12" screen
• Very easy to use
• Internal memory or SD card slot
• Wi-Fi
• VERY IMPORTANT: Remote operation by multiple parties possible

The frame is intended for the grandparents. All grandchildren should be able to upload pictures remotely, which will then automatically play on the frame. Therefore, once set up, nothing should need to be configured or changed on the picture frame itself. The grandparents are not tech-savvy and live a bit far away.

Remote image management, whether via app or website, is therefore essential!

Thanks.
