Hello Rauno,
the problem occured because flickr is moving their api to ssl and did a ‘blackout-test’ for developers on june 3rd, next blackout test will be on june 17th
see https://code.flickr.net/2014/04/30/flickr-api-going-ssl-only-on-june-27th-2014/
since i’m using photonic with flickr too, i’m hoping the photonic plugin will be updated soon
regards
