Flickr + Twitter = Flickr2Twitter? That appears to be what the photo-hosting site and the social-networking site have in mind.

Flickr2Twitter allows Flickr users to Tweet photos directly from the site, according to TechCrunch. Once users' Flickr and Twitter accounts are linked, the "Blog This" button on Flickr photos will feature Twitter as a distribution choice.

TechCrunch added that developers who want to add Flickr as a photo option to desktop and mobile clients can use Flickr's existing application-program interfaces.
