Check out the below link and plug in a word or two. The interface is seriously cool, with the search work it finds the related tags on pictures found on Fickr.
I tried it with my flickr account. I updated some of the tags on a few of the pictures and then tried the search. I pluged in "Brent Spiner", "Avery Brooks" and RPG into the above link. I got my pictures I had labled. Looked like update rate is only a min or two to show via the above search link.
