What about Copyrights and Likeness Rights?
This isn't a legal guide, just a brief summary about posting here. We aim to follow United States copyright and likeness rights laws, and it's your responsibility to make sure your uploaded images are within those laws. If in doubt, check
http://www.copyright.gov.
Copyrighted images cannot be posted without explicit permission from the copyright owner. "Someone put it up on the web" does NOT count as explicit permission.
Public domain images can be posted (this usually means at least 70 years old, or formally released into the public domain by the copyright owner) assuming you have permission of anyone recognizable in the image (or their estate if they have been dead less than 50 years).
Images you own can be posted by you if you have permission of anyone recognizable in the image. Posting your image here does not mean you surrender copyright, but it does mean you give permission for other users to retouch the image and upload here, unless you explicitly state otherwise at the time of uploading.
Images you don't own can be posted if permission is explicitly given by both the owner of the image and any recognizable person in the image.
Celebrity images or random images from Google or anywhere else on the internet cannot be posted unless explicit permission from both the photographer and the subject has been obtained.
Changing a copyrighted image in any way does not remove it from copyright.
Pieces of copyrighted images, no matter how small, retain their copyright and all the same rules apply.
"Fair use" and parody protection are problematic to define, but to be safe lets assume neither apply here.
You are responsible for obtaining any necessary permissions for images you upload, and you are liable should anyone choose to enforce their copyright or likeness rights.
