Climbing.jpg's author is mispelled, and license isn't mentioned

Investigating further, I see that most of the images seem to have problems. I've now looked through all but 6; I'll do the rest tomorrow.

The problems I found are as follows:

"O Life" (http://www.flickr.com/photos/irsen_flow/3806685902 ), "Bay" (http://www.flickr.com/photos/fstopper/2950042567/ ), "Frog" (http://www.flickr.com/photos/fstopper/3718165490/ ), and "Shoes" (http://www.flickr.com/photos/letoloke/2752418092/ ), " are labeled as All-rights-reserved on flickr -- so we'll need to track down what exactly license they agreed privately to offer to the Ubuntu project, or ask them again.

 "White Orchid" ( http://www.flickr.com/photos/forteller/48036068/ ), "Flor de Loto" (http://www.flickr.com/photos/pablomeneses/3218431048/ ), "Grass in A" (http://www.flickr.com/photos/andrewkneebone/3544313849/ ), Naranja" (http://www.flickr.com/photos/teleyinex/2945647308/ ), and "Palmengarten" (http://www.flickr.com/photos/rene-germany/1478690483/ ) are under CC-BY-SA-2.0 on flickr, not CC-BY-2.0, so we'll need to either get them changed, or include both licenses in the copyright file.

"Misty Morning" (http://www.flickr.com/photos/piotrzurek/1399412798/ ) is under CC-BY-NC-SA-2.0 on flickr, which isn't even acceptable for Ubuntu, I think. We'll need to check on that.

And "Butterfly.jpg" has no mention in the AUTHORS file at all, isn't in the Ubuntu Artwork Karmic Release Shortlist pool on Flickr, and isn't findable through TinEye (reverse image source). We need a source and license for this one.

OK, I've done the last 6, and 4 of them had problems.

"Floating Stones" (http://www.flickr.com/photos/fstopper/3586915842/ ) is labeled as All-rights-reserved on flickr.

The other one by Piotr, "Radioactive Sunrise" (http://www.flickr.com/photos/piotrzurek/645493473/ ) and "The Rainbow is Dead" ( http://www.flickr.com/photos/roomurdock/3294531381/ ) are under CC-BY-NC-SA-2.0 on flickr.

"Sunset" ( http://www.flickr.com/photos/difusa/2284799784/ ) is under CC-BY-NC-ND-2.0 on flickr, which is obviously unacceptable.

I concur that there was clearly a typo in Davin's name, and apologies for that.

The rest is (I believe) superseded (by several batches of new wallpapers).

For the licensing, the user is welcome to put them in any many places under as many licences as they wish.

Remember that for the high-resolution variants that actually shipped in the distro (most contributors don't have a Flickr Pro account anyway), the user has had to supply this separately. What is important is that these larger copies of the images *sent directly* are correctly licensed as CC-BY-SA or better.
