Can I use Wikimedia Commons images?
Last updated
TL;DR: A CC BY-SA 4.0 file, adapted and shared commercially: Yes. Every file on Wikimedia Commons has its own license (often CC BY-SA, CC BY or public domain), shown on the file page.
Is a CC BY-SA 4.0 file, adapted and shared commercially allowed under Creative Commons Attribution-ShareAlike 4.0 International?
Yes. Every use you described is granted by CC BY-SA 4.0, and nothing you described is prohibited.
License: Creative Commons Attribution-ShareAlike 4.0 International (CC-BY-SA-4.0, curated)
Duties: attribution, license_notice, state_changes, no_additional_restrictions, share_alike
What else should I know?
- Pass the file page URL as source_url to check_license and a2ally reads that file's declared license from Commons. Public-domain claims are marked for review.
What are the sources?
How can I check it myself (free, no key)?
