Why do I need a flickr api key?

Question

Reading through the Flickr API documentation it keeps stating I require an API key to use their REST protocols. I am only building a photo viewer, gathering information availabl

Answer 1

We set up an account and got an API key. The answer to the question is, yes there is advanced functionality with an API key when creating something like a simple photo viewer. The flickr.photos.search command has many more features for reciving an rss feed of images than the Public photo feed, such as only retrieving new photos since the last feed request (via the min_upload_date attribute) or searching for "safe photos" only.
