Image Question The type of license to use will depend on what type of permission the author gives you It could be GFDL Creative Commons Copyright Free Use or the author might decide to release to the public domain To credit the author do something like Image Zebra finch jpg The source can be the link back to the Flickr page Please post the text of the e mail granting permission on the image talk page like I did at Image talk Zebra finch jpg so there is no question about receiving permission Remember the e mail must be specific about what rights the author is granting not just permission but license under GFDL or permission for free use etc If the image on Flickr is already under a free license then you can just use the image and choose the same license as is used on Flickr And also it can not be a noncommercial type license or the image will eventually be deleted Regards
