Has fallen behind on the Flickr API
No longer works since the Flickr API changed to require SSL. Every access fails with a an error in the system.log:
Aug 3 20:49:16 mylaptop Multi Monitor Wallpaper[3577]: flickr request failed: Error Domain=com.flickr Code=95 "The operation couldn’t be completed. SSL is required" UserInfo=0x6000002691c0 {NSLocalizedFailureReason=SSL is required}
Not bad when it works and they may fix it. Until then, not recommended for Flickr images.
