Images FOR Africa (IFA) collects pictures gathered from the field in Africa from Flickr users organized as a flickr group. Now we have 430 members and 6700 pictures where their owners are willing to license them under the terms of a Creative Commons license. If somebody wants to use a picture from the group, he/she has to check back if the picture is already Creative Commons, if not you have to ask the owner for a written permission exclusive for you. We thank Yahoo for providing Flickr.
