Regular visitors (thanks!) will notice that I’ve taken the public flickr photographs offline and replaced them with a selection of my own photos. This is not what I desired, however the creative commons licensed images on flickr are simply not representative enough and the better images that you get when using the public API to search for public images sadly resulted in a DMCA take down notice as flickr think it is appropriate to return copyright images in that particular feed.
I might have lived with using just the creative commons images, despite the huge impact on performance (flickr do not yet make it easy to purge copyright images) but after seeing too many portraits of pets and black and white images that had nothing to do with the golden-hour, I decided that until another source of photos available for non-commercial use becomes available, the use of flickr images will be withdrawn.
