Automattic the parent firm behind WordPress.com, and San Francisco-based PicApp, said today that the two firms have inked a deal to allow Wordpress.com bloggers to embed photos from PicApp at no charge. Wordpress.com was one of the last blogging platform to support PicApp's embedding, which previously worked on Blogger, Vox, Movabletype, Typepad, and Wordpress.org--but not Wordpress.com.
