wikiview is a Powerful Photo Browser for Exploring Wikimedia Commons

Wikimedia Commons has millions of public domain and freely-licensed photos available to the world, and now there's a powerful new tool that helps you dive into the ocean of imagery for exploring or locating exactly what you're looking for. It's called wikiview, and it's a graph-based visual image navigator.

Wikimedia Now Lets You Contribute to Its Archive With a New Smartphone App

If you're interested in donating your images to the public at large, Wikimedia Commons just made it that much easier. For a while now, their online media archive has brought together a huge library of free-to-use content under one roof; and because images uploaded to Commons must be licensed as public domain, GFDL, CC attribution, or CC attribution/share alike, everything is free to use and/or share.

Now Commons is releasing a new app (formerly only available in beta) that will allow users to upload photos to the Commons archive right from their phone and, it's their hope, encourage more people to contribute "high quality educational photos."
