A word about proper attributing.
Sometime ago I've simplified the rules of attribution for the what-ifs sake, while trying to satisfy the requirements set by Dave. Here's how it works:
Not all Wikimedia Commons images can be used simply by providing a link.
For example
this file:
Can only be used if you credit the author.
https://creativecommons.org/licenses/by-sa/3.0/deed.enIt, therefore, should look like this:
Source:
Wikimedia Commons. Author: Richard David Ramsey
If there's a clear public domain in play, as with this image:
You simply need to write "public domain" or "PD" in description:
Wikimedia Commons (PD)The same rule apply to non-commons images. Unless said image is either public domain, or free for use with crediting the author, it'll be considered a violation and dealt with pronto.
Here's an example for non-commons PD image:
Proper attribution:
Florida Memory (PD)I'll not be checking unsourced/improperly attributed pictures. These will be removed.
One more important note:
you have to provide a link to a page from where you took the photo, not an image link.
