Wikipedia:Image license migration

The licensing update will move Wikipedia from licensed under the GFDL to dual licensed under GFDL plus Creative Commons CC-BY-SA 3.0.

As a part of this transition, any images licensed under the GFDL and meeting certain conditions described below may also be dual licensed.

Media file relicensing criteria

To be eligible for relicensing, a file must meet the following conditions (set out in GFDL 1.3, section 11):

1. Must be licensed under the GFDL 1.3 (including e.g. "GFDL 1.2 or any later version", but not including "GFDL 1.2 only").
2. Must not be marked as having any "cover texts" or "invariant sections".
3. Must have been uploaded to Wikipedia or to some other Wikimedia project before August 1, 2009.
4. If first published under the GFDL somewhere other than a Wikimedia project, must have been uploaded to Wikipedia or to some other Wikimedia project before November 1, 2008.

Any file that meets these conditions may also be used under a Creative Commons {{cc-by-sa-3.0}} license as of June 15th, 2009.
