I’m a big fan of the new WordPress admin interface, especially the new media buttons that lets you quickly add photos, videos, and audio to your posts.
But what if you use Flickr for your photos? Well, there is a great plugin called WordPress Media Flickr, written by yu-ji. It adds a little Flickr media button, and makes adding a photo from your Flickr photostream a piece of cake.
His site is in Japanese, but he has a great screencast showing the plugin at work.
