how can i detect when flickr photos become unavailable?

How can I tell programatically when an embedded/blogged flickr image is replaced with a "photo no longer available" image?

With Ruby if possible.

Solution

  • You could use the Flickr flickr.photos.getPerms API method with the photo ID extracted from any URLs you have.

    http://www.flickr.com/services/api/flickr.photos.getPerms.html

    This would tell you if the photo is missing or has had it's permissions changed to prevent public viewing.

    Various Ruby wrappers are available for the Flickr API.
