We are starting to see more web sites dedicated to presenting images in picture frames on walls.
Electric Objects (www.electricobjects.com) provide high quality web-enabled displays and images to display. The screen has a matt surface, very pleasing colours, a portrait orientation and a “set-and-forget” picture setup process via a mobile phone app. The screen brightness changes with room brightness and can be set to turn on/off for night use when sleeping. I have one of these screens and will be buying more as they demonstrate my concept of Changing Static Images so well.
DAKboard (dakboard.com) is another company selling a web-enabled picture board. This seems to have a more web-information bias than just for personal photographs.
