I think the developer took MVP to the extreme. For legal reasons it's critical to fully explain the license on the photos available for download, and the terms for anybody submitting the photos. Unfortunately it's really not enough to just say: "Free hi-resolution photos for your website."
Hey, thanks for the comment. Looking to add something now. Apparently this is the most 'open' and least restrictive of the CC licenses: http://creativecommons.org/licenses/by/3.0/deed.en_US but it still says we would need to attribute the author which we don't require.
(Use the CC stuff if you can.)
