I’m writing a Wikipedia article about Cryptomator in Finnish and I’d like to upload some of the screenshots of the application on the Press Kit page to Wikimedia Commons.
However, there’s no mention of the Licensing for the screenshots. Wikimedia Commons guidelines state that users can’t upload images without clear permission or license stated by the author, I can’t therefore use the screenshots as is.
I’m asking if it’s OK to use those screenshots for this purpose, and if so, could an adequate license for them be added to the web page?
