I did something similar with the Philips frame, bought one for my parents and my in-laws and they both have their own dedicated galleries in a self-hosted Gallery2 installation, which allows me and the rest of my family to upload through the web, via email or directly from windows with the 'publish to the web' feature. Works great. Only complaint that I have with this frame is that it reloads every image every time it's shown, rather than caching it. Don't know why, it does cause high bandwidth usage :/
