Thanks to my friend Heshy , I discovered this new Wi-Fi LCD Frame. It can read Flickr RSS feeds and it can also display e-mailed photos. Although it costs $250, it, IMHO is a much better deal than the Ceiva Photo Frames, which require you to pay an annual subscription fee.
One of these days, I will convince my wife and siblings/siblings-in-law to buy this for my parents, in-laws and/or grandparents. All of us could e-mail new pictures to the phone and they would always have a fresh set.
