Template:License change/doc

Use this template for odd situations where the licensing for an image at its source was previously a free license, but later changed to a non-free license, to alleviate confusion. Licenses are perpetual and non-revocable, meaning that that changing the license stated still allows the image to be subjected to its previous license, unless it was created and published after the change. Only use this for media that went from free to non-free at their source, and not the other way around.

Usage
For instance, if the website now specifies Creative Commons Attribution Share-Alike Non-Commercial 3.0 (CC-BY-SA-NC-3.0), call the template as.
