[Commons-l] Need Advice on Image Permissions

[Rama Rama]

In short:

all image on Wikimedia Commons are Free. You can thus use them for any
purpose provided that you
1) give proper credits to the author and
2) mention the licence; the GFDL also requires that you put a link to
the text of the GFDL licence.

The licence of your web site will not by jeopardised by the use of a
GFDL image: the licence applies only to the image, not to the page
itself. The so-called "viral clause" of the GFDL and other Free
licence means that derivative of the images will be under the same
Free licence as the original; this does not apply for a web page,
since it is not a derivative of the image.

Cheers !
