This is cool and it is great that the software is all open source, but randomly clicking around it does seem that an awful lot of images all come from Flickr, with the images even being hosted by Flickr. It seems to me the interface could make the source more clear.
Thanks for your feedback! We don't host any of the images, we link people directly to the source. Flickr does have orders of magnitude more images than other providers. We will add making the source more prominent to our list of issues to fix.
