I am very happy to share the news of Dr. Yale Rosen's donation of images to Wikimedia Commons. He had shared over 2000 images related to pathology, many of which are rare images, during his long career as a pathologist. He used to run two Flickr streams, one for
Atlas of Medical Foreign Bodies and other for
pulmonary pathology images. I had first approached Dr. Rosen for donating a few images, but he kindly offered to donate his entire collection of approximately 2000 images plus the contents from his
pathology website for use on Wikimedia projects. He had shared several images under CC-BY-SA or lower in the past, but this month, he moved his two large collections to CC-BY-SA. All images from Dr. Rosen's Flickr streams are now available on Wikimedia Commons
here.
Please feel free to engage in categorizing, adding structured data and uptaking these images to Wikimedia projects. The naming and description of the files are accurate and straightforward, so I think it is possible for people without specialized knowledge in pathology to perform categorization and addition of structured data. Kindly write to me if you have any questions or comments.
