Love this little app. I think its ok because he only uses images with Free to Share licenses and then attributes the work to the original photographer.

ie this card http://kr.ma/h2

has an image that uses this license: http://creativecommons.org/licenses/by/2.0/deed.en_CA

Thanks! You got it - the Flickr images are pulled in via Flickr API and only CC-licensed images are made available.

I had a fun little exchange with a Flickr admin, so I'm even being more conservative than I need to be considering the site is non-commercial at the moment.
