[OGDev] Node images and copyright.

[Kake L Pugh]

Bob has a patch in Trac for adding copyright notices and links to licences
for node images:

You can see it in action here:

I'm going to be adding this to svn in some form, but it's been pointed out
on Flickr that the copyright symbol may not be the best one to use for
Creative Commons licensed images:

What do people think?
