Q. How can I contribute to World Explorer?

A. You may have contributed already! If you have a public, geotagged image on Flickr, then it was part of our computation. If you added tags to the photo, these tags were also analyized - and your photo might appear in the visualization (look for it!). We update our tag maps every few weeks, so newly uploaded photos could influence the next version of World Explorer.
