Wikimedia Commons donated a collection of photos of minerals

^{In the photo - Staurolite from the Murmansk region ( Keyvy ).}
Mineral collector Ph.D. Robert Lavinsky donated to Wikimedia Commons his full database of images on mindat.org (about 29,000) and all the images from his own page irocks.com . He also offered about 20 thousand additional photos from his archive for use when necessary. Wikimedia Commons requires assistance in translating, downloading, etc.

Prior to that, in 2009, the Amsterdam Museum Tropenmuseum issued under license CC-BY-SA 35 thousand photographs from the former Dutch colonies - Suriname and Indonesia. Everyone knows about earlier donations of the German Federal Archive (Bundesarchiv) (more than 80 thousand and wrote about it on Habré ) and Deutsche Fotothek (250 thousand).

There are about 6.3 million photos, video and audio files available on Wikipedia, copying, editing and commercial use on Wikipedia.

^{I hope everyone remembers that when using these pictures you need to specify the author (s) of the particular picture and its license, and not write nonsense like “Wikipedia photo” or “author: Wikipedia” (you can just as well write “author of the photo: found in Yandex ").}

If you are someone (well, the Prime Minister of the Russian Federation , for example) to break on the transfer of a couple of tens of thousands of photos, then you on Commons: Partnerships . And you can upload your own photos even now !
