The copyright status of a photo does not change when you post it in Panoramio. Photos are copyrighted according to the decision of the owner: standard copyright, copyleft, Creative Commons license, and so on.
When you post a photo in Panoramio, you grant Google the right to use it as follows:
Third parties who use the Panoramio API can display your photos, but they must credit you by displaying your name under the photo. Third parties are not allowed to download or copy your photos. More information is available in the API page and in the Terms of Service.
Please visit our DMCA page where you will find all the information on how to file a notice.
There are two ways that another site might legitimately display your photo:
A site that uses the Panoramio API can show photos that appear on Panoramio, free of charge. The site must credit the photographer and link to the original photo page. Sites that use the Panoramio API cannot store copies of the photos.
For more information about your rights, please review the Panoramio Terms of Use. In brief, the Terms of Use explain that you retain rights over photos that you upload to Panoramio, but that you allow Google to display the photos through services such as the Panoramio API.
However, if you suspect that the owner of another site copied your photo improperly, you'll need to contact that site to resolve things.
We can act only to resolve issues of copying within Panoramio. If someone copies your photos to another site, you'll need to take action yourself.
