is copyleft even a word? and i seriously doubt you will find any pics without a copyright - celebrity pictures are big business, by professionals or otherwise. why let people use them for free when there are companies paying $100+ for simple pics of C-listers?
great! if copyright, can be possible, then there should also be also a provision for left side copies! lol, just remember that old joke, "got a battery of exide", the sardar ji, replied, "dusra side ka kaun lagayega!!", anyways! go to santabanta, there you have got some pics. all are copyrighted, but them perhaps you can get there code inserted etc, and have the link. hi5 also gave there featured photo link to be inserted in website and blogs. even without the live hiperlink!! but if you want a copyright free, then you must take those photos yourself, there is no other options!
Copyleft pictures are genraly under copyright they just allow free use as long as you follow the terms of the lisence. Wikipedia has a few such pics such as http://en.wikipedia.org/wiki/Image:NaomiCampbell.jpg Other than that Flickr.
