Twitter API search within following

wondering if anyone has heard of a way to filter Twitter search results to the users 'following' list? I'd like to do a search for pics that people I follow have posted. The pics part is fairly trivial (search for image URLs) but I'm guessing th开发者_运维知识库at a user-filtered search is beyond the API, even with oAuth.

I've seen a couple of services like snapbird.org that advertise this feature (even though they don't seem to work well), any guesses as to how they go about this?

Thanks!

You can implement this specific image search easily with the help of jetwick.com available as open source here: https://github.com/karussell/Jetwick

Currently searching in your friends is possible but adding yet another filter isn't that hard. Patches are welcome ;)
