1,000 images identified via crowdsourcing
400 volunteer users have identified 1,000 images on Image Archive Online. In the last four weeks, more than 2,000 comments have been received under the rubric "Do you know more?" (external link).
We now know, for instance, that an aerial photograph taken by Walter Mittelholzer features a striking river course near Flawil. And we received a key piece of information on the village of Wiesendangen, which turned out to be Uhwiesen. We would like to take this opportunity to thank all the volunteers for their help.
