I'm working on a small project to help me tag content on Flickr.
I've been looking through the API and there's obvious ways to search for tagged content, but not a simple way of finding what content hasn't been tagged (without just looping through image ID's till I find one with no tag).
Has anyone come across this in the past and found an easy work around?
flickr.photos.getUntagged will do that for your own photos. I'm pretty sure that there's no way to do it for more general searches, other than brute force.
