Whose Is It?
If you are going to use Flickr.com then you MUST use ImageCodr.org!!!
Easy as 1, 2, 3. You enter the full url of the Flickr image, in return you’ll get html code and a brief license summary.
If the image is not licensed using Creative Commons you will see a, “Oops, the gremlins are here again!” and “This image is not license under a Creative Commons license and can not be used. You might ask the author to relicense the image.” Now how clear can that be???!!!
