how do i get a list of all tags used in a particular flickr set

Question

with the flickr API i want to find out all tags used in one particular set of photos.

i know it's easy to find out all my tags (via flickr.tags.getListUserPopular), but i don't know an easy way to limit the tags to the ones used in a particular set. checking every tag against teh photos in the set is too very slow.

There isn't a 1 step answer to this but you can get this using the existing APIs. Start with flickr.photosets.getList and flickr.photosets.getInfo APIs to get the list of photos (Photo IDs) in the set you want then use flickr.tags.getListPhoto to get the tags for each of the photos. Then create your tag histogram. These should be all available from any of the language interfaces to flickr.
