Some new restrictions on download for Free account are coming next May 15...
We’re rolling out a service update to Flickr’s download options for free accounts, and we want you to know what to expect. Starting May 15, Flickr will restrict downloads of original and large-size images (larger than 1024px) owned by free accounts. If you use a free account, this update applies to both your own content and to content shared by other free members.
